Photo Dojo's free, isn't it?
it was when it first came out.
No, but I wish it was.
For the DSi, you should get Photo Dojo. Very fun.
You should buy an game with you're ponits.
Theres a pretty good Mini-mario puzzle game on the DSi Store and North America has Cave Story on the DSi Store, so if you can, get that.
