awesome game for the gba, which is a lot considering that handheld is definitely not my fave when it comes to its game library...anyway, the story mode is pretty good, you get to play as a ton of characters with their own episode as the story progresses. this game can get pretty hard/challenging at times, although you can sort of customize the difficulty when fighting against emerl as whatever skills you have loaded for him is what you will fight against when a battle against emerl comes up in the story. i noticed the dialogue in this game is a bit different than in other sonic games, its a lot more lax and natural, which give these characters and story a bit more life. if you're not too good at fighting games like me its best to grind in sonic's story since the battles are the easiest there.
