UPBGE

Uchronia Project Blender Game Engine

upbge.org

A game-engine fully integrated in Blender.

OPINION: All 3D computer graphics software tool sets have a steep learning curve. It is not just Blender, they are all like that. So, let's keep this discussion simple. For newbies, think of UPBGE as just being Blender itself.  You  simply put UPBGE into a directory, change to that directory and type: ./blender.

UPBGE, is simply a full version of Blender, along with a game engine installed. If you are not ready to give the game engine a try, you can just use UPBGE, the same way yiu normally use  Blender.
