Dunno what PC games you've been playing but most games past 1995 use WASD now.
Oh yes! I play Starcraft, Supreme Commander, Giana Sisters, Dwarf Fortress, Nitronic Rush, Masters of Orion 2, Super Meat Boy and AI War all with WASD. /sarcasm
No, the games that use WASD are primarily first person shooters, which is a rather small part of the gaming market. To be honest, I haven't seen a single platformer that uses WASD lately. Anyone know of any?
