I haven't played Ultima Underwold I since 1998 (I believe), but I can still vividly remember its awe-inspiring architecture and amazing mechanics. Its atmosphere and engrossing gameplay also, but I digress. What you need to know is that said classic, innovative 3D RPG can be grabbed in its box via this Ultima Underworld: The Stygian Abyss (DOS) eBay auction.
The game comes in its box with four 3.5" disks, manual, background booklet, install guide, reference card, map, registration card, catalog and a couple of leaflets. Seller ships worldwide.
