+      Ultima VII, 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 that created an
+      Ultima VII 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 VII play the game on modern hardware, in
+      as close to (or perhaps even surpassing) its original splendor as is
+      possible.
