thanks, they don?t' have a about section but I gathered that it has features that make blender easier to use... Can you still build a level with blender for the normal crystal space, if so then I don't get the difference. Can both handle higher level polygons?
Well the point of GameBlender and CrystalBlend is to make games without coding. You make the game in Blender using logic bricks. Of course you can also use Blender to make levels for normal Crystal Space games that you make in C++.
