I know what you mean by this, its good actually seeing some running gameplay for it rather than quick cut shots. And I can see how the tone of the trailer might have put you off. It was easier to see here that it is actually a big budget AAA game.what makes you think it is a big budget AAA game? because it has a character editor?
Watch from 8:10 to 8:22 and you see all 3 characters feet are below the floor. doesn't really scream high effort to me...
