"It's a shame that the various playable characters in Ape Escape: Pumped & Primed aren't more varied, because, as it stands, it's difficult to imagine that anyone would be willing to play through the game's story mode more than once--particularly if a point is made to repeat events until everything is unlocked for a chosen character. As a party game, Pumped & Primed is nice insomuch that it should be easy for even your nongamer friends to pick up, but its appeal (despite the fact that it boasts such an impressive collection of monkeys) is limited, and it's certainly not a game that would justify the purchase of a multitap if you don't already own one."
