I would do that, but there's been a guy rummaging through backpacks lately. It's the only public place I can think of with those people too :(
1. Bring it without games in it [to avoid damage].
2. He may take it, possibly break it.
3. Snatch it if it's broken.
4. Take it to teacher and tell them he broke it.
5. They'll probably have to pay exact price for a new one.
If you don't want to take risks, wear cargo pants and put it in there to get 1: lots of steps, and 2: have it not bulge in jeans pockets, or he could see it.
