This is one of the turning point of PC gaming in my opinion. It pushed the limits of the PCs of its day. (It was one of the few times I had to write a custom autoexec.bat!) So I was delighted to see GOG release it, and for the Mac no less. Too bad the emulator is so poor. There are audio issues: sometimes the audio has "breaks," sometimes only one channel plays. Worse, there are major control issues. The keyboard is sluggish and sometimes locks up in one or two directions. A joystick is too fast to be controllable, and in-game calibration does nothing. Thus, the action sequences are unplayable! The game would get 5 stars, but the emulator is worth no more than 2.
