It's gonna be reviewed by yours truly, first-person shooter boy.
What I'm looking for is something that's well-executed within the constraints of the Wii hardware. In my mind, a good example of this is Mario Kart Wii, or Super Smash Bros. Brawl. In both of these cases the developer took what they had to work with, did some ingenius stuff, and really impressed me.
In other words, I'm not going to look at it like, "This isn't Halo 3 or CoD4, this blows".
