Besides the (usual) minor troubles with the AI behaviour (I'll get to that later, after more testing), I'm really having trouble with migration - did you change anything else in your mod than:
Code:
Race Starting Percent Reproduction := 8
Actually, the problem I'm having is that I have too few troubles, crazy as it sounds
Migration movement outwards from the homeworlds is so strong that I don't need any pop transports in the first 10, maybe even 20 turns or more. I started with 3 evenly sized homeworlds, and only those with "good" conditions barely keep their pop level, the other is slightly draining away with only 3 additional colonies founded in the starting systems.(no racial reproduction modifiers, no med labs build, "+12" means coloniser send out on that turn):
Code:
unpleas./domed - - - - 14 (6%migr./6%gr.)
good 66 103 123 139 176 (4%/10%)
unpleasent 2477 2461+12 2457 2453 2449 (8%/ 6%)
mild 2483 2474+12 2477 2480 2483 (7%/ 8%)
domed/good 17 18 19 20 21 (4%/10%)
mild 70 85 118 155 171 (5%/ 8%)
good 2485 2484+12 2485 2485 2485 (6%/10%)
I have never noticed such a pronounced effect of migration in SE before. Maybe because I normally go for medical tech/centers very early, and the added +1% growth overcoming the problem? Anyhow, homeworlds depleting on their own ain't that great IMHO.
edit: PS - Thanks for this mod, keep up the good work !!
