Ultima 7, an RPG from the early 1990's, still has a huge following. But,
being a DOS game with a very nonstandard memory manager, it is difficult
to run it on the latest computers. Exult is a project to create an
Ultima 7 game engine that runs on modern operating systems, capable of
using the data and graphics files that come with the game.

Exult aims to let those people who own Ultima 7 (copyright 1993) play
the game on modern hardware, in as close to (or perhaps even surpassing)
its original splendor as is possible. You need to own "Ultima 7: The
Black Gate" and/or "Ultima 7: Serpent Isle" and optionally the add-ons
(not required to run) in order to use Exult, and we encourage you to
buy a legal copy.
