SEGA really needs to do something awesome with Amy Rose one of these days. None of the games in the past few years have really done her justice.
The last main title she (or pretty much anyone not named Sonic) was even playable in was released in 2006... ever since then she's had a rather minor role, pretty much left out of the action for the most part. Things were much better for the pink hedgehog a decade ago. Hopefully the new TV show next year marks a new turning point.
