So the gist of his argument is that no one else is creating new worlds like they did in Bioshock. It is all New York (GTA) and Military Shooters(CoD, Battlefield, Medal of Honor, etc.) No one is doing historical fiction (Assassin's Creed, Red Dead Redemption, L.A. Noire) or SciFi (Halo, Killzone, Gears, Dead Space, Bulletstorm, Crysis, Homefront, Rage, Resistance) . He totally ignores the fantasy genre, which I can kind of understand since they all have similar worlds, but some are well designed and have strong storytelling. Basically, he is full of crap, and I think he knows it and knows that getting a lot of people to disagree with you is a good way to get some publicity for your new game.
