This is a fantastic party game that flew under the radar of most gamers back 2004, and even now as most people tend to gloss over it when talking about ape escape. Nonetheless, Pumped and primed is great for both playing by yourself and other people, The game is not a mario party clone, it's all minigames. But the minigames have have a very high skill ceiling and customizing your character is not only tons of fun, but it's something that as far as I know, only this game and it's sequel Million Monkeys have done, I can't think of any other party game that let's you basically let's you choose your character's equipment, appearance, summons, and name.
I really hope Ape Escape comes back one day, alongside this game and the franchise as a whole.
