Could someone please explain how to install/setup or otherwise get pygame working in Pythonista, so you can run games or other multimedia apps (such as music, animation, etc.) that are based on Pygame?
If it is not supported then please add my vote for pygame support.
Pygame isn't supported in Pythonista, right now anyway. It probably wouldn't be too difficult to write a wrapper of it using the scene module, but most Pygame games rely on mouse and keyboard, so it wouldn't be to much more work to make it use the scene module if you're already rewriting it for touch.
