Ranked in these QuestionsQuestion Ranking
Pro 3D support
Since pyglet is so tightly woven with OpenGL it allows the support of drawing in 3D.
Works with Windows, Linux, and OS X.
Pro Written in pure Python
A small advantage, but being a core Python developer, it may be the best to stick to the roots and develop with pyglet as it is able to compile using other Python interpreters.
Con Small community/popularity
There is a decent amount of documentation and API to go along with pyglet, but in terms of community support there seems to be very little.
