This is just a matter of curiosity. I started developing an openGL game engine with AndEngine 2d, and I was wondering which engines use large sw at home to develop a game.
Thank you very much.
Unity3d is used by many professional software developers and homes. It is very popular because of its simplicity, and many consider it the best engine among those who cost less than a million dollars.
Those who develop popular high-level games use purchased / developed engines specially for themselves, many of which are quite expensive.
Another example is Unreal Engine.
Here is the list: http://www.xing.com/net/androids/android-game-engines-engines-list-553242/android-game-engines-engines-list-29951892/
min3d may be worth exploring.
