The AI could be improved in several ways, but is one of the most diffucult thigs to test since you have to play complete games every time you modify something to see if it has produced the desired effect.
We provide 2 AI difficulty levels, and you can play easier or more difficult games by playing with or against allied facions. (Tucho has won against 3 Ultra allied factions in the riverside map, but the AI has improved a bit since then).
