Race For the Crown is intended to be a kid-friendly, light-hearted game. The premise is that magical royal siblings have been told by their parents, the rulers of a magical kingdom, that the succession to the throne is in the hands of whoever uses their power to do the most good for the kingdom.
The kids will have to work to identify the dangers the kingdom faces, find ways to make their magic solve those dangers, and make sure their power doesn't go too far or do something unexpected. Along the way, they'll hopefully learn some life lessons about magic and responsibility.
I'm still writing RFTC, but it's probably not more than two pages' different from Inept Sorcerers itself.
