You didnt like Conflict Vietnam when it came out on regular Xbox a few years ago? I thought it was pretty decent.
I have a gaming gap in my life that stretched from "Legend of Zelda" to when the 360 came out. Some of it due to a succubus wife at the time and some due to making up for having a succubus wife.
I liked how you could upload your own music and play it during the game.
You can do that now. Just copy whatever music you want onto your 360 or jack it straight in, cut the game volume down, and open the 360 music player and hit play.
