I love family guy, its one of my favorite shows on Fox and Toonami. That and American Dad, but there's not a game out for that show, and after playing Family Guy for the Xbox and PS2, I was not impressed.
The Xbox has superior graphics, ( the Xbox versions always tend to look better), and while the dialog and voice acting is great, gameplay, repetition on levels, and simple gameplay, make for a weak game.
Its kinda like that Simpson's wrestling game. Big expecations, Big letdowns.
Its mostly button mashing, followed up my crazy missions that don't make any sense in the end.
But its family guy, the shows a blast, and I love all the crappy problems the producers had with the FCC. It just makes the show better.
If you love the shows, the game is great for a rental and spending a Saturday afternoon with some senseless button-mashing humor.
