@Frogboy - Treaties are broken
I'm pretty sure you're already aware (if not, check my link in your saved games thread), but research/trade treaties are broken.
Case in point:
I'm the #1 empire and have completely dominated the Resolyn down to literally 2 level 1 cities, both completely within my influence. A research treaty is +9 Tech Research per turn for me and +0 for them. It should clearly be the reverse. Trade Treaty<->Gold Production? Same thing.
