this is a more interesting title in the sonic series, that being a portable exclusive story-focused party fighter. Due to the "portable exclusive" part of that, I have never actually played this game with other people before, which kinda sucks considering the fact this is a fighting game here. The CPU are extremely cheesable due to some mechanics allowing you to get easy instant kills and stun-locks. The plot is weird, follows sonic and the gang as they go collect chaos emeralds to help restore a new robot characters memory. the OST is actually not that bad as well, considering the fact its on the GBA, which isnt really remembered for its audio quality. I think the plot ties into sonic advance 3 in a roundabout way but I never really got it. If you want some more sonic shenanigans and havent played this one yet, go for it. Don't expect to play the multiplayer anytime soon, though.
