Very special, but 'Unsupported'

I've played the demo quite a while and I was very impressed with the gameplay. It's well fun to play hotseat with your friends. All turns are calculated at the same time, but since on hotseat there's only one person at the PC at a time, you can hear Echo's of explosions and death comming from the other end of the room if your opponent sees the results of the turn first ;) All fun etc, but there's a problem.
I was looking into buying the game, but it seems it had a monthly fee attached to it. In my oppinion, such a fee for a game of this kind is a bit odd, but after a while I descided to give it a shot for a few months, to see the rest of the game. That is when I noticed the "buy now" button on the website doesn't work ;p. Not a very good way to make money I think. Anyway, I mailed to the contact adress and after a month I still haven't received a reply. No fullware play for me it seems. :-(
O well..
