Played my second game as the Yor, finally won an influence victory after eliminating two races. Observations and comments.
Played on a large map with random density of habitable planets - the setup gave ZERO -0- planets outside of home systems as habitable. That's why it went so long.
Everyone despised the YOR, yet were always willing to make them UP chair and UP HQ. Always voted for Galactic Peace and then went back to war asap.
The computer races were allowed to have negative treasuries, Krynn were at -6000 or so at one point -before I bought a bunch of their ships. Which is a great way to scout the home system since you can see what they see before they are hunted down. I was stopped from producing right after going negative until I could produce a positive revenue and treasury.
Once I conquered the first enemy world I never could get the Yor there to reproduce from the initial 5-7 population, even with researching the Spark techs.
