WIZARDS AND WARRIORS
http://www.mobygames.com/game/windows/wizards-warriors
an RPG from the year 2000 by DW Bradley.
I've had this game since it came out but never got a chance to play it. I've been very impressed with it. Very cool gameplay and huge, atmospheric dungeons.
It can be tricky to get working on a modern system with an Nvidia card since it was designed for Windows 95/98. ATI cards work fine. I have Windows XP with an Nvidia 9800GT but I finally got it all sorted out
