Well, the more I mess with it, the harder this mod is to do. Here are some of the considerations:
I have about 10 alien races. 7 of them need access to General Products hulls (puppeteer), and then have *similar* techs but not absolutely congruent. Then I have 3 races which need completely independant tech trees (Pak, Thrint, Tnuctip). So what I really need is more logic operators in the TechAreas and Facilities then I have. or I can build lots of basically duplicate items and balloon the files waaaaay up there
Then there is the issue of behavior and realism. First, puppeteers are going to act like an incredibly powerful neutral, they have already started their great migration and don't really want to interract with anyone.
Then, we need some different colonizing/utilization parameters. For instance, Pak and Kzin are definitely going to want to make facility-size defense units for planets, sattelites and platforms and orbital bases not withstanding.
Would the Pak bother with planets that breeders couldn't live on? Sure, maybe as weapons facilities or automated mining yards. But you would definitely treat them differently.
And everybody would have orbital laboratories, we need that in the code
Starting conditions: how do I start the Kdat as slaves of the Kzin? How do I start the belters and Flatlanders in the same system and have them cooperative?
Dyson structures will make my head hurt
so will planetary-sized cannon...and the fact that there are no warp points in the niven universe (damm these hard scientists
) And yes, it would also be nice to have better ways to trade stuff, like GP Hulls
==================================================
And so, I'm still thinking about Known Space, but I'm also thinking about the Mote Universe of Niven and Pournelle: warp points, langston fields, saurons, moties, MacArthur and Lenin battlecruisers, etceteras.
And there is the universe of the Merchanters Alliance (merchanters/cyteen/earth company)...the hinder stars, very big stations at important stars, very few planets, warp point travel, Mazziani Strike carriers with riderships full of space marines (Commander Edmund Porey aboard the carrier Africa)....
