On the flip side, anyone doing a Korx Major mod is never going to have their work redone.
-edit
This does Galciv 3's personality types a disservice, as we have so much variety in between these now but:
Snathi, Yor, Drengin - Evil
Thalan, Iridium, krynn - Neutral
Iconian, Human, Altarian - Good
Races seem perfectly balanced.
The expansion will now likely mean we need an extra one in there to keep it 100% square modwise, hopefully we'll get another DLC down the line to keep us balanced
but I don't know their ideologies as I don't yet have it.
I was also a fan of the korath, as I like the idea of sub factions, a branch of humanity which is much less 'nice' for example would be a faction i'd support wholeheartedly.
