I just found the game too. Someone in a Heroes of Might and Magic forum recommended it, so I went on and tried the demo. I'm impressed, now playing the full version.
The game looks extremely rich in content, great musical score, interface gives lots of info and the gameplay is open, by the looks of it. This'll keep me hooked for a while!
I'll need to browse this forum now, to see if I can find help with some gameplay basics...
