The difference is that MS and Sony have started porting their games to PC this generation. There's very few console exclusives left apart from Nintendo
The PC would've survived even without that though. Not saying this isn't good, of course. I'm glad to see this happening, as I would've never gone the console route ever again. If you want to buy consoles for exclusives, then you'd have to get all three platforms, maybe even the handhelds (although that's kinda the only thing for Nintendo now anyway). It's like all those streaming services that you'd need if you want to watch all those exclusive TV shows. Who the hell is supposed to be able to afford all that? A PC may be potentially a bit more expensive, but I don't have to deal with any of that bullshit anymore after that and ultimately saving myself a lot of money and general trouble.

PC gaming survival hasn't been in question for decades. I think it's more about people wondering when consoles are going to start dying off, and we might be getting there soon
