I first got connected with my Mac 512e. A great computer, Mac Plus ROMs and a SCSI adapter for the 20 meg Jasmine drive, it was an incredible amount of storage.
Favorite two games:
Space Rogue. The Mac version was better then the PC version, higher res, etc.
Lunar Rescue. This was a 'lunar lander' type game, except that it was a side scroller and you had to deliver cargo between moon bases, some of which were underground. Flying a moon lander underground and having to lay down some fire on a gun on the roof, a real challenge. I remember, if you flew too high, you'd get shot down by the sky defense system. Very similar to Gravitar, iirc.
