I have a Mac OS version of Wizardry I (runs on the classic Mac OS, not X). I've been revisiting it the past couple weeks for the first time in about 10 years, and browsing lots of Wizardry websites during that time. I have yet to see any other reference to it. I feel like I'm the only one who's ever used it.
It's probably one of the most playable version. You can open a separate moveable window for each character's stats, and leave it open while you go through the maze and fight. There is a separate maze window. Although you can do anything with the mouse, can fly through the maze and battles with keyboard commands. Graphics are certainly a lot better than the old Apple ]< version I played 33 years ago, but not anything close to the PS1.[P>There are some subtle changes from the Apple ]<, but not much. Items use the newer naming (eg Armor of Lords instead of Lord's Garb). There are mapping crystals. Not really that useful for mapping, but I've never seen them mentioned elsewhere. Diadem of Malor is missing.[P>I think some of the monsters may be treated differently than the Apple ]< version. For example, I've seen lots of people mention that you can makanito giants, and monster lists show them with no spell resistance. With the Mac version they appear to be 95% spell resistant, except for Earth Giants. So basically you have to slash away at them. I recall this also being true of Apple >< version, but I'm not certain.[P>Another difference is that all characters start with 8 HP. Makes it a bit easier to survive until your first level gain.
The very sad thing about this version is that I don't believe they ever released wizardry 2 or 3 on the Mac, so it's a dead end. I'd love to play these scenarios, but don't want to go down the path of getting it running on some clunky emulator. I tried DOSBox with Wizardry 1 just to see how it worked and quickly said no way.
