Tried it a quite a few times on transcend, so far i've managed to do it three times with the moderate one city challenge rules (no way am i trying the hard,no military to speak of allowed rofl). Really annoying when the AI gets so cocky and starts bossing you around later in the game, you just wanna load up a new one, get some crawlers and smack it into place so hard ..
Best SP in this has to be the planetary datalinks, usually its useless in a sp game but if you can try and keep the AI in competition with each other you get alot of free techs.
And btw don't try this in a small map ... Yang has killed me twice now just simply breaking a treaty with surprise attack, in comes 30 planes wipes out all crawlers then 6 infantry and rovers appear right next to the base and game over
