Reminder that steam is not only "no longer supporting windows 7" ,. they will be actively disabling all clients on this OS by end of this year. No, you can't run offline. No, you can't run the games standalone. The official steam position is go fuck yourself. Their reasoning is due to intertwinement with some google features, which imo is just making it even fucking worse, because why the fuck do google need to be involved in me playing a game I bought in 2013? And why do they get to say I can no longer access this game?
If you want a workaround, hit up this but in future, just use GOG.
This isn't about the OS, so don't even start with me. Deliberately disabling access to items you've already purchased with no recourse is the highest order of bullshit.
