first, you wont be playing these games on 486 or integrated graphics, stop it.
particle effects in poe actually destroy my graphics card to under 60 fps
starcraft II was released what 2.5 years ago ? I really fail to see what a decade old franchise has to do with anything. battlefield is a decade old franchise too.
but even if you could, I dont really understand your point. do you play games for graphics or gameplay ? pc gamers can play games they love from 90s easily. console gamers are stuck with current gen games and have to switch back to old consoles to run anything. you'll be lucky if they rerelease shyt like they did MGS
there prolly wont ever be pc exclusives anymore with amazing graphics, just because the budget wont recoup and the game pretty much have to be multiplatform in order to. but there are lots of pc exclusives. yes, most of them are kb&m games
