The game engine, BGE, built into Blender was basically just killed off today. In this developer commit to the upcoming 2.8 source code ( https://developer.blender.org/rB159806140fd33e6ddab951c0f6f180cfbf927d38 ), you can see that MASSIVE code changes were made, that basically purged Blender Game Engine from Blender 2.8.
