Actually, if I combined the Yagudo and Beastmen into one civ (since several of the FF IX civs are using some of those cities), I could add it in about 15 minutes.... Most of the UUs could be scrounged from all the Orcs/Orks that TGA, Muffins, Aaglo, Embryodead and Kinboat made, and there are already at least 2 Orc/goblin LH. Hell, I might even make them playable for those of a sadistic bent... I mean I do have the Forbidden Land Eureka from FF III with Great Tyrant Zande from FF III as a playable civ... Instead of getting paladins with Monothesim, they get skeletons, who can enslave defeated units into MORE skeletons, and instead of a swordmaste with Mythril Forging, they get a Lamia, and instead of the Advanced Airship with Makou Power, they get the Flying Fortress that Hyne was ruler of. Therefore a playable beastman civ will not be out of the question. Of course, it WILL get the "Evil" flavor, meaning it starts with the worst possible default relations with any "Good" civs...
For the Orc/Beastmen UUs, There are a number of Orc melee that could be used as an Orcish Protector... Probably either Kinboat's Uruk-Hai or Aaglo's Black Orc. I think that I'll have the Orcish Warmachine as a Tank or Heavy Tank replacement and use either the WH 40K Ork Dreadnaught, WH 40K Killer Kanz or Mega Ork for that. As for the third UU, probably an Orcish Warchief that uses one of the melee orcs that I didn't use before and will either be a Swordmaster or samurai replacement (depends on where the Warmachine goes, so that the Orcs, like everyone else, have at least one UU in the modern age)... All that leaves is the Culture group for these orcs...
And no it doesn't look that bad for using not-quite FF games, especially Seiken Densetsu, since (a) technically the first Seiken Densetsu was CALLED FF Adventure, (b) the series has a lot in common with FF, and (c) they were made by the same company....
Besides you seem to forget that I have the civs from FF I (and I'm using 8-Bit Theater as the basis for FF I), so expect to possibly see up to 4 civs from that game alone, FF II, and FF MQ to add as well. The Espers would never work as a civ for the fact that the unique summon tech for the FF VI civs is Espers, and the Esper Statues is the SW that produces the FF VI summon every 5 turns (haven't decided what their summon will be yet, and won't until I get around to editing the modern tech tree which will be around the time that the cows come home, unless I get some help with the hard stuff, like units and LH).
And the Mithra and Rangers DO have to do with Selbina, since Selbina is a big stop for Adventurers, and I just wanted an excuse to make another Mithra unit

For Selbina's third UU, I was thinking a "Scavenger" or "Treasure Hunter" unit that replaces the Marine would work.... They'd be more or less like the Al Bhed Machina Hunter, but without the stealth attack (the WOULD be able to "salvage" defeated enemies to create Death Machines like the Machina hunter)..... I just need to find the graphics that would work... Oh, well, time to search through the forums for some orky things....
