Crunchbattle
My six-year old son Noah invented a "video game" at school called Crunchbattle. It was made from a folded piece of cardstock for the screen and controls with another piece of cardstock taped on the back as a battery pack. Here's an illustration:

Crunchbattle has the same basic design and control layout as the Gameboy Advance SP. My son doesn't have a Gameboy Advance and he mostly plays video games on the computer, so he must have seen one at school or at a friend's house. Also, Crunchbattle doesn't have any room for cartridges. It's a single-purpose unit, just like the old Mattel Classic Football.
Considering it was made by a kid in grade one, I think it's a pretty smart representation of a video game. But most of all, I like the name. Crunchbattle. That's a great name.
