Out of curiosity, are there any other games or perhaps a genre you might compare the game to? It sounds pretty interesting, and it looks gorgeous.

Also, how would you rate the control scheme? Is a USB controller an option, or is it K+M only? Would one have an advantage over the other? I tend to prefer K+M games these days but find that a lot of times, depending on the game, it can be a pretty sizeable handicap to play that way.
