There is also an Ultima Atlas included in the box, which features all the navigation maps from the first eight Ultima games, and the box itself offers a special Inside Cover, which shows a time-line of the Ultima games included.
While the games are DOS only, some of the bonus content requires Windows.
The CD contains a registered copy of Mo'Slo, a program needed to slow down some of the older games.
Note that the box cover shown on the back for Ultima II is a mock-up: You will not find that package, as it does not exist. Ultima II was only released by Sierra, and, as Sierra rather than Origin owns the game's cover art, the package designers went with the "Wrong Way" Dennis Loubet cover from California Pacific's re-release of Akalabeth (the precursor to Ultima).
