Right- I tended to play SMAC instead of SMACX because of the balance issues (or, at least, play it with just the original 7 because it did add new buildings and secret projects) and the new 7 had weird divisions. The Corporation and the University seem like natural divides- but, say, the Angels were just odd ("We're super hackers!" "Wouldn't that make sense for a gang inside another civilization, rather than a full civilization?").
Yeah, I tend to agree. My favorite mix is playing as University, with the Gaians, Peacekeepers, Cybernetic, Planet Cult, and Believers, with one of the progenitor factions to make things interesting.
