It looks to be a quality game.
"Best game ever"? It depends what criteria you set, so that's largely an irrelevant description. From the brief gameplay I saw there, it appears that Devil May Cry will be the one to beat - if it beats DMC, I'll happily crown it 'best action/shooter game ever'. Too difficult to go contrasting THAT kinda thing with, say, Starcraft or Riven though.
What's with all the hate on this guy promoting it tho? He seems pretty funny, and he's obviously got experience or skill in the industry.
