Hey,
I was wondering is Xenonauts made with an engine or did you all go from the ground-up(using SDL+OpenGl, etc, etc).
The reason I ask is related to porting the game over to other systems. It sometimes is easier to port things over when it is made from the ground-up then using engines, but it is also true visa-versa.
I hope to hear from you all soon.
Correct me if I'm wrong, but it looks like you all are using C++ and OpenGl with SDL for sounds and input...
