because it's linux and you can develop your game the same way you do it for your desktop PC, or for the other handhelds (that would be an advantage if you want to submit a game for multiple platforms)
Dingux is quite popular, although from what I have heard, native is even more popular in some regions of the world (like China or Brasil).
If i'm gonna to compete, I'll produce a game for Dingux, so that's the platform I'd like to see in the competition.
But anyway, why don't we allow both native and dingux?
PS. Do the games need to be genuine and written from scratch from the moment the competition starts, or can I submit a game I have already worked on for a few months and that a competition would be a good excuse to finish?
