Sorcerer! Beautiful mirrored backglass and artwork. Typical System 9 gameplay. Not quite the feature set of System 11s, but the simple yet brutal gameplay keeps me coming back. It's my favorite game in my small collection.
Some of the CPR translight to backglass conversions mentioned here (EATPM for instance) don't look as good as the original translight. On the other hand, PPS' repro Sorcerer backglass is top-notch--better than my original. So, since your main draw is the backglass, no worries if you find one with backglass issues. PPS nailed it.
