Can someone explain to me the purpose of Blender Game Engine?

I think the BGE’s situation is a little more than just ‘being in maintenance mode’ when you take into account new features that work in it like LOD, enhanced actuators, collision layers, the light data node, multi-threaded animation, anti-aliased shadows, ect…

My poor wording - I didn’t mean the BGE is currently in maintenance mode, just that its possible it stays in Blender, but is (mostly) in maintenance mode, Similar to OpenCollada or Blender-Internal-Renderer.
