Installs fine, but crashes hard when run, forcing a reboot. Don't see why, as this isn't a very intensive game. I'm using Crossover Games 7.1.1 and OS 10.5.4, with the commercial disc version of SR2. Stardock has a digital download version without Starforce, but I haven't tried it. Starforce could have something to do with it. Anyone have any ideas? The only other game that forces a system reboot as of now is S.T.A.L.K.E.R.
