Chris Blundell at www.plutonicdesign.com told me he is highly impressed by the free editor and that it creates better game levels than found in the game!

• good documentation
• demo assets (see http://developer.nvidia.com/object/udk.html)
• radiosity
• scripting interaction potential
• free! (I may mention this quite a bit)

But.. still only for PC..I do wonder how much it costs for a game to go commercial though when sold as an educational game by an educational institute-hundreds of thousands? Or do they take a percentage of the profits (which seems a more desirable option!)

It seems to me that a free game editor is one great leap for indie and educational games (i.e. Unity, XNA-kind of, UDK) but there also needs to be a cheap path to Playstation 3 or XBox..any such pathway out there? Perhaps Blender can be ported to Playstation or XBox?
