I think Cyclops is being overly harsh. I played this (ver1 I think) to the 85th round and thoroughly enjoyed myself. At that point my save file died so I was unable to continue :(
There are an enormous number of independents and opponents are tough, but if Queen E can get away with it in Athendore why can't Sajinn? I really enjoyed churning out sphinxes and building up stacks of dominated indies. The AI opponents are willing to ally initially so you can dodge the effects of fire mastery and domain. By the time they turn on you, defences should be strong enough to resist. Just for the record, I took Whitefang and the tigrans.
I won't rate this because I didn't finish the map, but recommend it to anyone looking for a lengthy and challenging session of empire building. Congrats to the author!
