jbergmann: I actually have The Ultimate Wizardry Archives, and they all worked on my Windows 7 64-bit computer :)
Same here. Before getting Wizardry 6 - 8 here, I had installed the games in an XP virtual machine as the installer is a 16-bit program that can't be run in x64, then figured out how to move Wizardry Gold over to my main system. Worked great. =)
For Wizardry 1 - 5, I installed those into D-Fend Reloaded along with a script I'd modified from Starflight to manage saved games. I don't play them very often, but every once in awhile I get the urge to beat on Werdna again (or have Werdna beat on the heroes, heh).
Edit: I wouldn't mind seeing Nemesis here either. It's the only game in the series I haven't played yet. I've played pretty much all of the games otherwise, including the later North American JRPG releases.
