I emailed the developers a while back. While they were flattered that there was such interest for a Macintosh version they told me they are focused on creating the best Windows games on the market and developing a top notch digital distribution platform (Impulse) to go with it. I was saddened but it it's a great game and they have a good attitude toward their customers. They didn't seem interested in Ciderizing a Mac version either because it would likely result in a subpar experience. I feel like this game would do pretty well for the mac crowd, it runs on some meager hardware so the Mini's with GMA chips would likely be able to run it. Feral are you listening? PORT THIS GAME.
The game is pretty amazing, I can imagine it getting boring if you just play against the AI but we get 3-6 people together and have some 4-8 hour marathon sessions of this game. Humans are very unpredictable and really amp up the play of this game (especially since there is no story mode persay).
