Just played a round with my friend with two unfair AI and promptly discovered a world of pain (still won though). I was wondering... what are the exact increases and benefits that Unfair AI get?

(I also noticed that Unfair AI tend to be extremely afraid of a few turrets and maybe one ship, so it's entirely possible to turtle forever since they won't attack you as long as you have a couple of turrets and a ship or two in the system.)
