I am looking for information on ease of use, preferably pythonic and up to date. But perhaps most importantly active.
After working with Pygame, Cocos2d, and Pyglet to create a series of games, I would have to recommend Pyglet.
Cocos2d and Pygame were very unwieldy. On the other hand, pyglet has a very neat API, enjoyable to work with, and very 'clean'.
It also has no external dependencies, and is wrapped on top of OpenGL, allowing you to do some pretty advanced special effects.
You can view a game (along with the source code) I created with Pyglet here.
