Currently playing TA 2.02, Immense map (tough setting) and all races (9) set to intelligent.
The races I've made contact with so far show the following mix:
Yor - Federalists/Imperial gov.
Arceans - Pacifists/Imperial gov.
Drengin - War Party/Rebublic gov.
Terran Alliance - Mercantile/Imperial gov.
So far, things look a little more interesting and varied compared to previous games (1.96).
I'm not sure (have to check the journals/logs) but I think the AI may have been tweaked a bit in the 2.0 and 2.02 versions.
