I recently joined this game run out of the US, and am quite intrigued. It's an old-school hand-moderated RPG/nation-state conflict game, a little less free form than Glory of Kings, and much more high magic and fantasy.
It's run more as a labor of love than a business, so as a consequence it's both cheaper than you would expect to pay, and much slower to process. I've not yet had a chance to run a turn, but wanted to call attention to it for those who like this sort of thing.
