Fun stuff to listen to, but I have a small quip: Evolve technically isn't in the co-op genre. It's 1v4 competitive multiplayer. The teams aren't even, but it's still a competitive game. Co-op in terms of games means players vs. NPCs. If there's a mode where you can fight an AI monster (which I imagine there will be), then that would be co-op. But the mode you played is just MP. It's just like in Left 4 Dead: the main game is co-op, but the Versus mode is not because it's 4v4.
I guess Sony's Project Morpheus was not out for demo? Don't think I've seen any outlet talk about being able to try it, but I could just be overlooking it.
