Read before you buy
Buy this only if you use an old OS X version and do not plan on using controller. This game is unusable on newer OS X versions, probably whatever came out after the end of 2011. This can be solved relatively easy, read here: https://steamcommunity.com/app/33440/discussions/0/521643320373002244/. Note however that controllers are not supported, the only option is to use keyboard and mouse.
