What is the project the more active/Stable? Can you say me the deep diference between cocos2D and andengine?
I'm using AndEngine for one of my projects, and I must say, it's rather nice. A little comparision between LibGDX and AndEngine:
1) AndEngine
GL
functions.2) LibGDX
The question is, do you need the LibGDX platform freedom, or maybe you are making project only for Android?
Also, look at that nice list of Android engines here.
