what political state are the bedu going into?
i dont remember the 3rd ed federal theocracy in detail, but ISTR that their assimilation of conquered races hinged on growth population. does the reduced growth rate in this game slow down how fast the bedu are going to be digested? 'cause that could be really sad for the mintek, with the D'Broaches breathing down their necks and Warp Point Drano entering the meta.
The Bedu refugees currently have a trade & military treaty with the Bjering, but as I said in another post, I think they will ultimately join with the Bjering due to the fact that they weren't able to get enough people out to amount to a medium population.
The pop growth thing is for when they have peaceful relations with an unsuspecting race. For assimilation after conquest it works a little differently. After conquest a d10 is rolled every turn and the total is recorded. Once the total exceeds the number of PU on the world then the population is considered assimilated and is now a full member of the conquering race. This is cumbersome, though, and it means that a world with a large or very large population won't be converted during the realistic time frame of the campaign. A full-sized very large population has 3,200 PU. At an average of 5 PU per turn (assuming 1d10 per turn averages 5), it will take 640 turns to convert the entire population. This isn't much of an advantage for the Federal Theocracies. You should be able to go through the normal conquest rules and then political machinations and end up with an amalgamated partner in much less time, making this useless. Instead, I've decided that the Federal Theocracy only has to amass 10% of the points it would normal need before the large or very large population is converted. In other words, you don't have to convert everyone, just the important ones, and scare everyone else into complacency.
