Emmet sounds way too much like Drake to me. That is, he's just going to be another realistic looking "human" summoning random crap on the screen (like Drake and his barrels). It's just annoying to see.
I can see them being a lot different. Emmet's all about building bases, so instead of throwing Barrels around, he'll be making little bases to camp out in and shoot at people, possibly placing Turrets as well. Tower Defense~ :D
(At least, that's how I assume he'll work based on StarHawk. No clue what'll really happen.)
