"Primitive" tech tree

[Jourin]

The mod I designed for me has some primitive tech called Space Travel and Basic Propulsion.

Space Travel gets you a Space Plane with three engines 100KT. Basic Propulsion gets a Nuclear Engine that cost 5X ion and burns 2.5x fuel. Basic Propulsion 4, plus Physics 1 gets you Nuclear Fusion a little better engine. Basic Propulsion 6, plus Physics 2 gets you the standard Ion engine.

Since I am using Physics for propulsion I bumped all the other physic prerequites by 1, ie shields are now Physics 2.

Space Travel 2 gets you the colony ship and Space Travel 3 gets you the small transport plus a small armed merchant ship (ie a small transport modified) With construction 1, industry 1, and Space Travel 3 you can now research ship construction.

This slows down the rapid expansion and makes the homeworld system much more important. Of Course I had to modify all the AT Reaserch files and some of the ship construction files.

Just a nit-pick, fusion drives are more advanced that Ion Engines (Which we have and use today)... Fission Rockets are about the same "level", the diffrence is speed to fuel usage... The Nuclear Engine I think your refering to is an ORION ENGINE, they are fairly fast, good on fuel but increadibly expensive! Chemicle Rockets would be the first "engine" used in a primitive line, the speed is good but fuel consumption should be at least 10x that of ion!

OK, just a status update:

I've scrapped the semi-prmitive section. Right now I'm working backwards from the SE4 tech tree; once I've dropped it down to High-tech primitive starting levels, I'll post a beta for people to check out.
