i've read the tutorial for creating the little game.
It have some bunch of programming, but it's ok.

And it's for owners of 3DSAMX (export animated models with ActorX).
If you make and sell a game, you'll have to possess a legal version of 3DSMAX :
Any organism or Discreet company could ask you :
you use UT3 engine , so show us you have a legal version

Not for all indie people, when you see the price of 3DSMAX today.

Cryteck engine have lot more power and powerfull editor, and a real complete terrain engine.
I don't think you will see this last one for Free.
