Well I’ve stumbled over this a few times before in my researches – here is the official thread, all 75 pages of it http://blenderartists.org/forum/showthread.php?107108-quot-Krum-quot-Work-in-progress/page75 in which a lone intrepid individual labors for 5 years to create the game of their dreams within the Blender Game Engine.

Update: sorry, 76 pages
