To make it quick and dirty - I'm a newb programmer who's looking hard at Pyglet, it looks like a really clean and friendly module to use, unlike something like PyGame which is, even by looking with my own inexperienced eyes, a beast.
However. PyGame is constantly being used, updated, reused by lots of people and seems to have quite a following. Pyglet hasn't been updated since January 2010. Most works of art are never finished, only abandoned - but two years and it's still on v 1.1.4 seems troubling.
So while I might be specifically asking about Pyglet vs. PyGame, I'm also not, because it leads me wonder about other ghostly modules that might be lurking out there, that had promise once upon a time but, for some reason, got dropped or shoved in a corner and aren't really relevant. Are such abandoned projects not worth the time and brain-space investment?
