Martian Dreams, also known by its full title, Ultima: Worlds of Adventure 2 - Martian Dreams, is a role-playing game developed and published by Origin Systems and released for DOS in 1991. It is the second game in the Ultima: Worlds of Adventure series. Like Ultima: Savage Empire, the game uses a modified version of the engine from Ultima VI: The False Prophet. The story revolves around The Avatar accidentally being shot from a giant cannon to Mars along with several Victorian-era dignitaries.
I do not own this game, and have not beaten it.
I have never played this game for more than a couple minutes, although I haven't heard many positive reviews about it.
Like most Origin titles, the game had a wealth of interesting manuals and maps to pore over.
