One of my all-time favourite games. It's very expressive, very fast, and very silly, all fitting the Nickelodeon brand, but it manages to be mostly fair with some great, unique ideas. The graphical style pops out really well, looking like vibrant toys instead of real characters, a perfect fit for this premise; the movesets aren't overcomplicated and instead hide obscured nuance - there's a lot of secret things you can do with characters' tools that you have to figure out yourself; the gameplay is completely its own, you can see a lot of cues from Smash 64 (the best Smash game) but it's ultimately unlike anything I've played before or since (including its own highly disapointing sequel). I have no complaints in the areas where it matters, except maybe RPS. RPS sucks.
