To Crytek and, mainly, EA, Crysis 2 was not a failure, even though technically it was a lot worse than the original/Warhead. To them, the $$$ means everything, and the rest F*** all...
So as long as us gamers keep on buying the PC version (minority), and the console versions (vast majority) keep selling like hot cakes, they'll keep making the dumbed down console versions.... And that, my friends, is the trend of every organisation with interest to making profits... :/
