I'd say Bioware needs to step in every time Sega thinks they have to use a serious storyline to write. Sure, the writing wasn't great, but it sure is better than some of the plots in modern Sonic games.
Regarding the game itself, what really bugged me, for the small amount I played, was how you HAD to do the little EBA rythm thingies all the way to get any benefit. Why couldn't it work like Shadow Hearts, and just have it so 100% success does more damage/gives a greater effect?
