I'll make the Borg. They'd need heavy Research, Repair, Range, Speed, Defense, Weapons, Loyalty (They're cyborg drones, please), Morale (They're cyborg drones, please), Influence (Not quite Cultural Assimilation...), Creativity, and Soldering bonuses. Negatives on Trade, Trade Routes, Diplomacy, Courage, Logistics (Who's ever seen a Borg fleet?). Their party? The Collectivists.
Yeah, I think they're overpowered.
I can picture the Klingons with Courage, Soldering, Weapons, Defense, and Luck bonuses.
