Was this just recently ported to Mac? I bought it over in Windows on Steam and just noticed it in my list of Mac games. I had pretty high hopes, since it's done by Aspyr, but it's a pretty awful port. No 360 controller support, no ability to change the resolution. Hell, you can't even navigate the menus with a mouse. Keyboard only. I was pretty excited to play this natively on OS X, but these issues make it not worth it.
