A lot of PC RPG exclusives are missing. PC is going to have it's biggest year in 2011, much because of it's RPG exclusives lineup:
- Diablo III
- Guild Wars 2
- Torchlight II
- The Witcher 2
- Neverwinter
- Star Wars: The Old Republic
- Darkspore
- Grim Dawn
- Drakensange Online
- Tera
- Rift
- Stellar Dawn
- Dead State
And more, but these are enough for now.
PC is having 6 HUGE RPG exclusives: Diablo III, GW2, The Witcher 2, Neverwinter, SW:TOR, and Torchlight 2.
Plus, also a few RPGs that come from veteran RPG developers, such as Grim Dawn and Rift.
There's also Darkspore, which looks quite impressive so far.
