dude... cities skyline just released...
Pretty much this.
Not to mention Star Citizen, DOTA 2, and plenty of others.
Star citizen isnt out for a long time isnt it?
Even though OP is technically wrong, I see the point being made. There really isnt that much. It seems like the only AAA games PC is keeping are the ones that cant be played using a gamepad.
Star Citizen is out, it has a modular release cycle so many parts of it are already playable. Also, PC has access to mods which add tons of playtime by themselves, along with the most played AAA exclusives currently out (LoL and DOTA 2).
Let's also not forget that PCs have MMOs, most of which never make it over to console. Guild Wars 2, Star Wars: The Old Republic, and Wildstar are all recent AAA PC exclusives, with huge playerbases. Not to mention other MMOs which are still going strong with new expansions, like World of Warcraft and Eve Online.
So yeah, PC has plenty of AAA exclusives. Sure, they aren't "traditional" exclusives, but in terms of playerbase and popularity, they are just as big or even much bigger than console exclusives. There are also hundreds of exclusive visual novels or indie games, many that are really good.
Edit: Oh, and Pillars of Eternity just came out today too. That's pretty much a AAA game already in the style of Baldur's Gate, and has a 93 on Metacritic.
