Coders go there own way. DoctorJ to assume the Lead Coder on Theme Park Builder 3D. The_Cook will be going his own way. His package as he originally maintained is a CAD package not a game whereas TPB3D originally was referred to as a Game, so the two paths went in differing directions. As for AlabamaCajun he has his own park game he is developing and has decided to develop that in a friendly and competitive mode. So he will be going off, forming his own community while we will continue development on TPB3D in the original direction it should have gone over 3 years ago.
