Speaking of Sonic, Sonic Adventure 2. The level design is mediocre and completely undermined the openness of the first one, but even if you take the entire main quest as a mildly-fun series of mini games through which you collect things for your Chao, it's worth the money. I've played Sonic Adventure 2: Battle more than most games, I think. Couldn't get enough Chao.
(And the fact that we haven't gotten another Chao game baffles me to this day.)
