I think this might be a Canadian exclusive? Anyway, I got to try it tonight. I was neither The One nor part of The Mob - I was just in The Crowd, which was still fun. You get to play along and compare your score against three random fellow players. I wouldn't schedule my week around this, but if I happened to have a few free hours while a game was going on, I'm fine with giving it a try.
One of the questions was "Which recent Academy Award nominee appeared at Wrestlemania XXV?" with the choices being Hulk Hogan, Mickey Rourke, and The Rock. I was surprised how many people got it wrong.
Yes, it's true! My brother-in-law bought it the other day and it is a blast! The different modes are all cool, with Hardcore (a game of keep-away with the Hardcore Title Belt) and Iron Man (Most kills in a time limit) being the best ones I've played.
