Olsson, I would like to propose a Tech Tree idea. Have you anticipated using a Tech Tree? If I may, I would like to work with one of your team members on that idea. I am a long time programmer. And, I really like how Empyrion: Galactic game does their Tech Tree. You already have a good start on it with your Research Machine. I would just like to plan out a full path of tech from most primitive to advanced. The project is now so new, this area has not been revealed yet. It would be my pleasure to help a bit in this area as I have good experience in this subject.
