Like I said, apples and oranges.
After several months of 3D game engine research, I don't think you can find a better deal than this. I actually got my game license before it went up to $200. I got it for $100 and that includes a lifetime of updates. Even at $200 that's a steal. GE is almost $100 bucks for a year, but what about after 3 years? $300?
The game that you're talking about is just the demo game. The engine comes with full source code, world editor, model viewer, etc. It's features are aimed towards next-gen game development.
Anyway, to each their own. Both C4 and GE aim at different game developer audiences, so I can understand your reactions to it. But as the topic is titled, I hopefully shed a little light on another area of game development.
