[Agema]

I've played LA Atlantis, and whilst I didn't win, I consider them to be potentially very powerful. Bear in mind the Hall of Honour mostly has games that doesn't include the new underwater mages LA Atlantis got which expand it into astral (S1/S2) and fire (F1).

I've played EA Atlantis. My perception is that what you need to get their magic good in the late game tallies pretty badly with the blesses that best benefit the Basalt Kings and sacred troops. Meanwhile the troops are too weak against Oceania and poor MR makes them a liability against Rlyeh. Basalt Kings are wonderful, but the nation as a whole left me underwhelmed.
