I read about Plato in Matt Barton's Dungeons and Desktops. I was amazed to see the screenshots and could see the likeness and wasn't sure whether you'd used it. Credit where credit is due but that doesn't lessen your achievements. Wizardry was all sorts of awesome - especially to a 12 year old D&D player in 82.
Ah - now here's a question. In the manual there's a screenshot of a location that wasn't in the game, talking about stairs with a turnstile (uhmmm searching on net - ok, on page 26 of pdf here http://www.oldgames.sk/en/game/wizardry-1-proving-grounds-of-the-mad-overlord/
). Was that in an early version and taken out?
