SOMEONE IS FINALLY SAYING THIS

FFVII AFFECTION MECHANICS LIST

Probably this article was better suited for Valentine's day but I'm not well known for my perfect timing... :)

I thought it could be useful to have a full list of the OG variables that affect the date mechanics, a description of the actual Remake mechanics and the differences between the two games all in one post.

I had initially planned to add here also the Wall Market dress mechanics but this post is long enough and the Remake dresses are just so amazing that they absolutely deserve their own post and my complete devotion💖

So...Let’s get to the list!  

OG AFFECTION POINTS

A reminder before reading:

Not all the optional choices of the game affect the scores.

Not all the optional choices that affect the score are mandatory.

Only four characters are associated to the affection mechanics and they start the game with different pre-set scores: Aerith 50, Tifa 30, Yuffie 10*, Barret 0. Aerith and Tifa are the most probable outcomes for the date.

The two main events influenced by the affection points are the Gold Saucer date and the scene under the Highwind. The charcter who has the highest score will spend a night with Cloud at the Gold Saucer; the dialogue between Cloud and Tifa before the final battle will be more explicitly romantic if Tifa has at least 50 points.

The characters are not in competition with each others, most of the choices affect the points of just one character at a time and sometimes they even affect uniformly more than a character. As a general rule, the points increase when Cloud tries to be a kind person and decrease when he's willfully mean.

The outcomes for the date and the HW scene can be different: it's not necessary to achieve Tifa's date to get the high affection HW scene, nor dating Aerith automatically triggers the low affection version. It is perfectly possible to get both Aerith's date and the high affection scene with Tifa.

***

REMAKE AFFECTION POINTS

Even though the Remake covers just the Midgar section, the developers payed homage to the Gold Saucer dates including a beautiful "Resolution scene" at the beginning of Chapter 14, where Aerith, Tifa or Barret will appear and talk to Cloud.

What determines the optional cutscene this time is the number of side quests completed during Chapter 3 and Chapter 8, namely the two chapters spent building up Cloud's merc reputation with Tifa and with Aerith.

The Remake affection mechanics are very simple: 

Aerith and Tifa start as equals. 

The player can complete 6 Odd Jobs and 1 final Discovery Quest, each one granting to the related girl +2 points. 

The girl Cloud will interact first after landing in the sewers will gain an additional +1 point that will eventually serve as tiebreaker. 

As you can guess, the girl with the highest score will lead the optional cutscene but if both girls have less than 5 points then Barret's scene will be unlocked.

PERSONAL THOUGHTS:

The Remake affection mechanics are significantly different from those of the OG. Funnily enough some free-answer dialogues still exist, however not only they don't affect the score but they're also illusory choices as the plot is very linear (see below).

The Remake mechanics are less romance-based. Sure, accomplishing the side quests can be seen as Cloud spending valuable time with the girls, anyway they spend the day doing rough and mundane activities like defeat monsters, rescue kids and search for cats. The focus will always be to improve Cloud's reputation as a reliable merc. Moreover, it doesn’t really make sense to consider Barret as being positively impressed by Cloud refusing to help people in need. 

While in the original Cloud can have just one date and one of the two versions of the Highwind scene, the Resolution scenes are not mutually exclusive and it's perfectly possible that all of them take place during the same night.

***

OG AND REMAKE COMPARISON

Most of the situations linked to the affection points in the OG changed or were left out from the Remake. In general Remake-Cloud tends to be kind with both Aerith and Tifa and by the end of the game his relationship with Barret improves as well. 

Tifa’s journey and resolve

As we’ve previously discussed, when Tifa first discovered Cloud at the train station, she found herself faced with a dilemma: she could heedlessly tell Cloud what she knows and risk losing him physically or mentally; or she could build up her resolve and wait for the opportune moment to tell him, hoping that with proper timing, she’d be able to tell him without losing him. Tifa chooses the latter.

Tifa wrestles with her secret across Midgar, Kalm, Gongaga, and Cosmo Canyon, but her worries finally push her over the edge at Gold Saucer’s Ghost Hotel. While Red XIII worries that he may go mad, Tifa is the only one who realizes that this is likely what is happening to Cloud; that Cloud may very well be going mad already. In her fear, Tifa snaps:

Red XIII: Cloud… I’m number 13. Am I going to go mad too?

Tifa: I don’t know what Hojo did to you, but you’ve been all right so far, right?

Red XIII: But…

Tifa: Be strong.

Red XIII: But, I…

Tifa: Stop it, Red XIII! Be strong!

Cloud: Tifa?

Tifa: You’re not the only one who’s worried!

(Source)

This uncharacteristic outburst convinces her. She has to talk to Cloud–and if she can’t find the opportune moment, she’ll make one.

So… she asks Cloud out on a date.

And the opportune moment reveals itself on the gondola:

Tifa: Ok, I’m going to just go ahead and say it…

Cloud: …what?

Tifa: Aeris would be able to just come out and say it, probably. Cloud… Sometimes being old friends is hard. I mean, timing is everything.

Cloud: Yeah…

Tifa: Cloud…? I……

Tifa: ………………….

(Source)

The gondola script looks like an attempted romantic confession–but much like everything else pre-Lifestream, looks can be deceiving. Given Tifa’s earlier emotional outburst, it’s far likelier that her words are hinting at her worries. But regardless of the interpretation, as “Interrupted by Fireworks” swells in the background, Tifa can only think of one thing: “I need to tell him.” Be it her doubts or her affections, could it be that now is finally the right time?

Surrounded by the flash and glitter of the Gold Saucer, Tifa hesitates… and before she knows it, the ride is over. Tifa lacks the confidence and resolve to be open with Cloud, and she allows the opportune moment to slip through her fingers.

Like Tifa said, timing is everything, and she never gets an opportunity like this again. As soon as they get off the gondola, Cait Sith’s actions set off a rapid-fire chain of events that culminates at the Norther Crater.

And suddenly, all of Tifa’s worst fears are realized. She loses Cloud mentally. She loses Cloud physically. He is gone. All of her careful, calculated efforts were for naught. Tifa is left bereft and depressed.

Which brings us to Mideel:

Tifa: What’s the matter? Are you all alone?

(dog whimpers)

Tifa: You got lost didn’t you? Separated from someone you love? Silly thing…

(Source)

This moment is huge for Tifa. This is the first time she is able to articulate, even indirectly, any of the thoughts locked away in her heart. Between Northern Crater and this moment, Tifa has changed.

And just in time. Tifa learns that Cloud may be alive and near. Filled with hope, “Interrupted by Fireworks” swells in the background and harks back to that moment on the gondola, when Tifa could only think of one thing: “I need to tell him.” And this time, Tifa is not going to let the moment slip through her fingers.

Final thoughts:

This makes Cloud’s clone status all the more heartbreaking. Just when Tifa thinks that Cloud is safe and she can finally make up for missed opportunities, Cloud is not ready to hear her. Once again she’s lost her chance and she’s lost Cloud. We all know Remake is going to rip our hearts out with this scene.

Damn this doctor is extra af, way to twist the knife (and explain why Tifa stays with Cloud):

“Timing is everything.” Tifa is right–from Cait Sith’s treachery through to Cloud’s clone violence, Tifa never gets the chance to talk to Cloud in private. By the time Cloud wakes up at the Gongaga Inn, his ego is at the brink of collapsing into full Sephiroth Copy mode–and if he got even a hint that Tifa doubts him, his ego would simply collapse sooner, same as it does later at Northern Crater. Tifa senses this, and hopes that fake confidence in Cloud will tide him over. This is also why she asks to stay in the party when the group goes to take on Sephiroth–she wants to keep an eye on him and support him, not just “settle things with Sephiroth.”

“Timing is everything,” reemphasized. Through the Lifestream sequence, we realize that even if Tifa had opened up to Cloud earlier, nothing would have changed–Cloud wasn’t ready to face his own flaws and work resolutely towards the truth with no reservations. The right time really is after Northern Crater and in the Lifestream. 

In an upcoming (mostly written!) post I’ll talk more about how “Interrupted by Fireworks” is actually a clever device to subvert our expectations… for both girls. There’s a lot of interesting symmetry that makes the divergences even more striking.

Special shoutout to @janeiteoftheslums​ who pointed out a detail I missed in the first (extremely short-lived!!) version of this post. Thank you so much! Everyone, if you’re craving some cloti goodness, head on over and read some of her fics.

What makes the identification of a character should start at their character construction—as a writer, this is when you’re determining the existence of this character, the motivation that drives their agency and purpose in the story (or even that of the story itself), etc. If this is layered [depth], only then would I personally say they’re a “complex character”.

What flows through that and becomes a part of the character’s “dynamic range”, like their personality and the range of elements attached to their character that is shown in different situations—like the, “this character acted this way here”, and “they showed this there”, “they have this significant item to represent this”, etc. This can easily be synonymous to that construction, or it can really just be it’s own thing if written that way. This in of itself can be interesting and “layered” in the sense that there is variety, hence the “dynamic range” terminology, but the understanding of that is different than what is for the sake of describing a character’s depth for identification. I would argue this is defined at the construction stage as opposed to in the counted showings of dynamic range, that otherwise, doesn’t have to be dependent upon what’s established in the construction. If you can see the flow in the range, chances are it started at the construction either way. A character’s growth is also NOT what defines their complexity, but that too can be synonymous to the construction and flow through for better storytelling. If their purpose is what changes and adds layers, depths—the WHY to what their purpose is, the it definitely applies. In most cases, you’d hope it does, but of course, you can have character’s undergo change for a specific element (or just learn something, becoming better on that front), but what sets their purpose is still 1 layer. Basically, the “lesson learned” could be an isolated thing that doesn’t really interact with their purpose as a character.

And to make it clear, whether a character is “complex” or not DOES NOT determine if they’re a good/poorly written character. I will never not stop fighting that as the art of simplicity or “less is more” is literally a thing that translates in a lot of different things. A simple character can absolutely be fine.

This is really primarily in the perspective of how we identify characters and really why—at least on this level of identification (things like complex, simple, protagonist, antagonist, etc.), the construction level makes more sense than the conditional moments alone. And it can be important as to not create a misleading, if inefficient label on the character. You can’t just identify a character as a “fan-service character” because the author wrote a few moments like that (which is typically more about their style than it is about the character), or if to go even more general, to be like, this is a “video game character” for a character that originated and immediate source material is that of a “anime or manga”. Like, the type of answer you’d give if you’re answering “who is this?” Of course, complex vs simple is a weird answer to give, but if for the sake of identifying FOR a character’s existence, then the logic still applies.

Some examples I’d look at are three well known shonen protags of Naruto, Goku, and Luffy.

Matchy-matchy 👑🥲

FFVII Remake Easter Eggs and compilation continuity - Part 9: EXTRAS

     CLOUD’S SECRET

Now everything makes sense

“HAIRTONIC Ideal Scalp Care. For astonishingly radiant & spiky hair!”.

     TASSELLATION

This particoular tassellation, alternating squares and octagons, present in many parts of the Remake, appeared also in other previous parts of the compilation.

     VICTORY POSES

After the victories at the Colosseum and in the Shinra combat simulator, the characters perform their OG victory poses.

     WEAPONS

If the player finds Corneo’s secret stashes they can fins three tiaras (Ruby, Emerald and Diamond tiaras) inspired to the OG Ruby, Emerald and Diamond Weapons.

     NATURAL OASIS

While in Trace of Two Pasts is stated that Elmyra’s house was full of flowers and plants even before the arrival of Aerith, it surely isn’t a coincidence that the sector she lives in, contrary to the rest of Midgar, is full of nature. Moreover the orphanage near her house is called “Leaf House” and the name of the teacher is Mrs Folia (”leaf” in Latin). 

     STARGAZER HEIGHTS

The place where Tifa lives in Sector 7, and where she suggests Cloud to live too, is a wooden building called Stargazer Heights, which is a reference to the water tower where they shared the promise. I’d say also that the presence in the same building of a black caped man isn’t a coincidence, considering that the first time these beings bould be spotted in the OG was indeed Nibelheim. 

     MATCHING OUTFITS

Tifa: Be sure to pick an outfit that goes with mine, okay?

Cloud: Will do.

Nailed it. 

Jokes aside there’s a subtle clever mechanism behind the choice of the Wall Market dresses. 

- If the player prefers Tifa, they’ll probably choose the refined dress and will have a good chance to get Chocobo Sam’s odd jobs (giving answers a bit more pro Tifa), so both Cloud and Tifa will wear the blue outfits.

- If the player prefers Aerith, they’ll maybe choose the sporty dress and will have a good chance to get Madam M’s odd jobs (giving answers a bit more pro Aerith), so both Cloud and Tifa will wear the satin outfits.

     BARRET’S DEATH

I’m not totally sure here if this was intentional, but when I saw Barret’s death I couldn’t help but think that during the first drafts of the OG he was the one who had to die instead of Aerith.

     CAPED CREATURES

We don’t know yet if there’s any connection between the Whispers and the Black caped men, but it’s hard not to notice the visual similarity of their designs. 

     BOOKS AND ADS

- PROFESSOR GAST

In Aerith’s childhood room in Shinra HQ there’s a book about the Lifestream written by Gast Farmeis, Aerith’s father.

- FAN CLUBS

In the same room there’s also a book about Stamp mentioning his fan club, which is an element that comes from Crisis Core 

- COSTA DEL SOL

There are some signs in Sector 8 - more a music disk - about Costa del Sol.

- FFVI

In one of the ads inside the trains there’s a FFVI quote from an author called “Gabbiani” - Setzer’s last name. 

- FFX-2

In Shinra’s museum there’s a picture with a FFX-2 character, Shinra.

Photo mode allows the player to restore the true colors of Elmyra's flashback.

As it turns out, when Elmyra adopts Aerith the ribbon is green.

(image source)

Aerith's ribbon: is it still a gift from Zack?

It has been rumored by some fans that the Crisis Core scene where Zack gave Aerith the pink ribbon is no more canon, because kid Aerith has a pink ribbon too.

I don't mean to sound pretentious but...they're evidently different. Kid Aerith's ribbon has four ends, adult Aerith's ribbon has just two.

Since the original FFVII kid Aerith's had two outfits. She wore the blue outfit in the first part of Elmyra's flashback and the orange one when Tseng tried to convince her to return to Shinra.

In the Remake she wears the orange outfit only in the train graveyard vision and the blue one in all of Elmyra's flashback, from the moment she found her at the station up to when Tseng showed up. It's definitely not very evident because of the sepia tone filter, but we can compare her dress to the concept art and to the orange dress: she has no ribbon on the chest but wears a pinafore dress and a light shirt with bell sleeves.

This means that in the sepia toned scene she was wearing the green ribbon, as we can see from the concept art.

The scene at the train graveyard bears many similarities with the situation described in Picturing the Past, so she was wearing the orange outfit before escaping Shinra HQ.

When Elmyra found her and brought her in Sector 5 she had the green ribbon, not the pink one.

Someone tried to say Aerith stated the ribbon was a gift from her mother when she met Cloud at the church...

Nice try, but she was talking about White Materia. (Leaving a couple of links in case anybody wanted to check: OG, Remake)

So, not only there's no evidence that the pink ribbon is no more Zack's gift but that scene influenced also an important moment of the Remake: Aerith and Cloud's first encounter.

And in both cases the gift was made in order to thank the other for their help

CC: To show you my gratitude for that "hello" that woke me up.

Remake: You know, for scaring those things away.

Ehhh...can I say what a coincidence again?

FFVII Remake Easter Eggs and compilation continuity - Part 4: DIRGE OF CERBERUS

[Includes: DoC Online Multiplayer - DoC - DoC Lost Episode]

SHINRA’S DARKEST SECRET

In Chapter 3, Weimar tells Cloud and Tifa of the rumors about undregroud secret labs. In Chapter 13, after the plate fall, Cloud, Barret and Tifa enter this mysterious underground facility full of monsters and Mako tanks.

7R: There’s a crazy story about a Shinra research lab hidden right beneath our feet - under the slums.

DoC: Deepground soldiers. (...) The shadow of the Shinra company, constructed by the former president and completely hidden from the rest of the world. (...) His goal was to create an army of superhuman warriors - not once letting morality interfere.

  INTERMISSION

During Intermission it is not only confirmed the existence of Deepground but Yuffie and Sonon fight against some soldiers in their DoC uniforms.

Nero: "Team"? Fool. There are no "teams" in Deepground.

Yuffie: Deep...ground?

Nero: The place where my brother and I like to play.

WEISS AND NERO

After getting to Deepground Yuffie and Sonon had to fight against one of the Deepground Tsviets, Nero. Meanwhile Weiss was added as a boss fight in the Shinra Combat Simulator. 

VITUAL REALITY

The overall concept of Shinra using VR simulators comes from DoC. In particoular, in DoC Multiplayer SOLDIERs and Tsviets used to train exclusively in VR arenas. 

MOOGLE YUFFIE

During the first half of Intermission Yuffie wears a tattered cloak with a moogle hood. This piece of clothing appeared for the first time in Dirge of Cerberus. 

This is Cloud and Roche to me
