I don't suppose that you'd be willing to license out the source code for the engine? Or any kind of deal-making concerning the source code? Curious; what is the engine's actual name? I've just been calling it FSM. Anyway, I'm really enjoying working with it! I wish I could make my own changes to it, adding features and whatnot, given that it's simply in a support stage now.
The source code is messy and is not recommended to be read by anyone )
No, really. It has a long legacy pieces that I never got to remove and is in any way held by ducktape and prayers.
The real name is Easy FPS Editor as I didn't think of anything better. I might release the soure code in future, but not now.
I wonder though; why would you need it?
