This game was fun to play, but the title of the game is midleading a bit. This really should be its own rainbow game considering none of it is in vegas!!!. Well it might be, but there were no casino firefights or anything like that, so you would never know this was set in Las Vegas. Other then that, and the serious issue of when you kill someone the game freezes for a second, it was fan and the multiplayer is good for the PSP.
