If we have two Elven civs, then one should be Moriquendi or Avari(the regular elves) and the other one should be a combination of the Sindar and the Noldor (the ones that fought Morgoth and Sauron, who sail away on the swan ships, etc.). Might as well call the second type Calaquendi. 'Course, I'd prefer having Moriquendi, Sindar, and Noldor running around -- but what do I know? That probably will wreck gameplay or something, beats me.
I actually would like Dunland in as a civ, even if they are barbarians. At least that way there isn't a giant gaping space in-between the Shire and Isengard/Rohan on our W.M.E. map. Or...maybe we could integrate Dunland into the Isengard civ, so then it wouldn't be a "one-city civ"???
Hobbits, yes please.
Free peoples, sure, sounds nice to me. Maybe a cooler name? Have to think about that...
Either Angmar or Mountain Orcs would be nice (just "Orcs" by themselves would be a more parsimonious name), because we need some annoying baddies running around the North too!

Or not, again, I have no idea what this would do to gameplay.
Arnor, uh, gee, I have no idea. Hmmm. The thing about Arnor and Angmar is that they were such fleeting realms. They didn't last long. Hmmmm...
No Valinor. I believe I already railed against that suggestion a few
threads ago.
Umbar included with Haradrim, sure, sounds like a decent compromise to me.
Gaia, sure, whatever, I don't know enough about how that would work or wouldn't work. Course we shouldn't call it Gaia, but "Arda" or something like that. We could even call it "Manwe and Yavanna" (for the Eagles and the Ents???). Sounds crazy, though.
But aren't we waiting for PCH or Celeborn or mrtn or somebody to tell us their grand ideas about the Civs that they've been working on behind the scenes for the last while? I'd like to hear about what they've been up to!
