Far Cry 2 wasn't your average FPS, incorporating heavy survival elements which made for some very divisive reception among fans. If you happen to be in the camp that hated them, Far Cry 3 should be your ticket.
The game will drop weapon degradation, the physical map, and the need to drop pills as your character -- Jason Brody, "a man at the edge of the world" -- isn't diseased. Survival is still an element, though it's not clear yet exactly how.
As well, the world will be less open; developers Massive Entertainment and Ubisoft are aiming to create a tigher experience this time around. Whether this means mostly linear and boring or action-packed and fun as hell, we'll have to wait and see.
