Has it ever been considered? Or is Mac gaming a "verboten" topic? Because I'm a Mac gamer/loser, and I love seeing what PC stuff is happening for MNC, and I'd love to get on board with that!
There's definitely a market for it. It's definitely not as big as the PC market. And adding in extra compatibility never hurt anyone! I know I probably won't be the only one who would buy it.
Uber doesn't have enough developers to expand to a third platform in the near future I think. If you really like MNC, why not simply dual boot Windows?
Wouldn't compatibility depend partially on the Engine itself? I don't think it would matter that much though. I doubt anything short of a Mac Pro (with the higher end GPU) can max out this game(mainly due to Apple's poor video driver optimization for games), and we all know how ludicrous the price is.
