Anyone have any recent experience with this game? I'm wondering if it runs well nowadays on 10.8.3 or if it has any known problems, crashes, etc. It was kinda hard to get a feeling for this looking at feedback on the App Store. The game hasn't seen an update for two years now but maybe it hasn't needed one either. I'd be playing it on a mid-2011 27" iMac with 12 gigs RAM and 6970m GPU with 10.8.3 if I buy it.
