One of the things that make Family Guy so riotously funny is how the salty jokes come fast and furious over the span of each half-hour episode. Stretch those same laughs over 8 hours or so of generally humdrum gaming, and the whole affair gets diluted to the point where fans will find themselves reaching for the DVDs instead of the game controller.
Oafish dumbass dad Peter takes a hard one to the noggin and becomes convinced that the citizens of Quahog are disguised henchmen of TV's Mr. Belvedere. Meanwhile, Brian is again accused of impregnating Carter Pewterschmidt's racing dog, and Stewie faces off against his arch-nemesis and half-brother (don't ask) Bertram.
As a result of these disparate setups, Family Guy is really three games in one. Peter kicks and punches through everything in sight, Brian sneaks past screen after screen of cops, and Stewie lasers and mind-controls his way to victory.
Unfortunately, only the last of these is enjoyable, and the non-sequitur mini-games barely qualify as such. Peter might be fun to watch as he cycles through hooker, soul brother, and default costumes, but he isn't much fun to play. The attack animations, like a characteristically idiotic attempt at jump-kicking, are satisfyingly goofy, but this sort of mindless combat just doesn't cut the mustard anymore.
