Strong numbers here for a fun game, and this number only tracks retail sales, not steam, which is where a vast majority of PC gamers got their copy. It's going to be interesting to see when L4D 2 is launched, since this game performed far stronger than I originally anticipated. Sure, I expected something over a million on the 360, and about the same of the PC, but Valve has got to very quite happy with it, and this was going directly into the maw of COD:WaW and Gears of War 2…that’s probably the most impressive stat about this performance!
