It's interesting to me actually. I'm not a fantasy type person. I've never really been interested in fantasy stories, books, game, etc. When I was a teenager, I dabbled in D&D, read a few Piers Anthony books, but that's about it. I have enjoyed a good fantasy film now and again, however.
Why was I attracted to this game? Well, I have to say at first that I was turned off by the overt evil of the game (I'm not into demonic stuff, etc. even if it is fantasy story). However, I AM into stories of Good vs. Evil with the ultimate triumph of good.
I decided to download the mod, and Woah! What an amazing feat. My very first game as Cardith Lorda (did I spell that right?) was VERY fun. I conquered an evil empire on "my" island, discovered "The Order" and converted the one neutral civ on the island to "Good." All civs on the island were good and declared war on the "Evil" civs on the other continent.
Good triumphed, of course.

. . . especially with my awesome Sphenor and other heroes.
I didn't quite understand the whole magic path with the "nodes" and other things. I've since started a couple of different games, and none of them have felt nearly as epic as my first game. I'm kind of surprised, actually.
That is the reason I decided to post here.
I thought, perhaps, I could relay to you that it would be nice if some element could be added to the game (through Python scripting or whatever) with which the sides of Good and Evil are more pronounced, insomuch as the "Good" guys are staunch allies, and the "Evil" guys finally decide to set aside a bit of their petty selfishness and gather their vast armies to defeat good.
I know you mentioned in your opening that this game is about good not always being perfectly good, etc. But I think you could make the differences somehow more pronounced. I find it very odd in a game that one of the Evil civs is attempting to befriend me, a good civ --which, in my role-playing, I never allow (I always choose "It ain't happening!").
Hmmm . . . just some observations, but I must say you truly have an amazing mod, even for someone "not into" fantasy!
