What she isn't a princess. Apparently people think this could happen and it will be a fun topic to discuss. I think if she were to get her own game it would play allot like Knights or Space Channel 5. She would have to fly around many different planets to try and rescue her star friends and maybe Peach, Mario, and whoever else the main villain decides to take that fine day. Your goal would be to fly through the gate at the end of the level while shooting opponents with your magic.
