There was a conversation about it over in this thread I had with Tolmekian (on page 2):

but here was the jist of it:
Me ->Question? when you play, do you also set all the AI personalities to Generic during game setup? I have found that by doing this, all civ's tend to expand much much better, and I am in my current Suicidal game, to see if it fixes the bug with the Torians and Iconians not building planetary improvements.
Tolmekian -> Yes. I currently set all the broken AIs to generic (11) - broken AIs being 7 (Drengin, Korath, and Yor) and 10 (Torian and Iconian). AIPs 11 and 8 seem to work just fine. Terran, Drath, Krynn, and Thalan use 8, while Altarian, Korx, and Arcean use 11. All the civs seem to be doing just fine. In fact, the Drengin are on fire in my suicidal game. I've got them at war with the other 5 AIs and they're dominating.
Me -> When you change a civ to 'Generic' do you or anyone know exactly what that civ 'loses'? For example, with Korath set to 'Generic' I never see them use Spore Ships, instead they use transports. Of course, they all still tend to go their specific moral routes (I've never seen Korath go good or neutral, or Torians go evil).
No answer to the above question yet. I do remember seeing some info about that somewhere, but can't remember where or what it said.
- Civ's still stay evil, good, neutral... generic won't change that.
- Civ's attitudes appear to stay the same also... it doesn't seem to do much to tell you the truth other than make them all play a bit more normal.. like they did in DA. Only thing I noticed was that Korath use Transports instead of Spore ships (like SS said). Of course I remember Korath always using Spore Ships in DA, but don't think I remember Korath ever using Spore Ships in ToA with their own personality or on generic.
- It's been verified (in my current game, as well as what others have said) that Torians and Iconians do indeed build social improvements on all planets when set to Generic, and they actually build them quite well, they seemed to use special tiles pretty darn good (except for farm tiles and culture tiles, which really dont matter too much).
So really as Tolmekin said, you just need to set Drengin, Korath, Yor, Iconians, and Torians to Generic, and the rest can stay how they are.
Setting Korath and Drengin on generic makes them both some tough civ's.. they really set out to be conquerers. Korath are especially nasty. In my current game, Thalans, Korath, and Drengin are all very powerful... But Korath fleets are flying around already with weapons in the hundreds, while I'm still at fleets with 80attack at most.
