First, I'd like to say that this game sounds WONDERFUL, and a lot like something my ds9 would cook up. He is often devoting sheets and sheets to new clubs or games he's working on. They could really have a time together. A bit like Calvin Ball!

As far as being 'too out there', Draw Wars might be something that only kids who are confident about drawing would enjoy, but it could turn out to encourage other kids to draw more!

Ds enjoys dungeons and dragons, and I keep meaning to get a copy of pictionary, too because I think he'd enjoy it.
Lately he has been making drawings of various star wars ships and mounting them with small paper handles then giving them to the other kids to fly around during recess or at his after school program. He just started making these little hand held faces with big mouths that move, too. It seems the other kids are in to them...and he is certainly enjoying making them.
