I agree that a direct answer would be best
I do find this funny...
Q: Will there be a way to edit my FPS Creator game in DarkBASIC Professional?
A: Yes. While FPS Creator itself will not generate any DarkBASIC Professional source code, we have released the entire source to the game engine part of FPS Creator free of charge to the community. This means that with the full version of DarkBASIC Professional, Upgrade 5.9 (or later) and the Enhancements Pack,
you can modify and recompile the game engine source code
as you wish. You are
free to sell on whatever changes you make.

Seems to go against the license agreement, does it not?
Anyway, lets wait and see.
