I'm using L3DT to build terrains for the Torque Shader Engine. Maybe some day I'll make a game, but for now I'm having fun learning all the aspects of game design. For me learning is where most of the fun lies.
It sure doesn't pay the bills though. =P
Nuts to reality...
Anyway, hats off to Aaron for having a big head full of brains. Thanks for making L3DT available to us.
