This is the freeware release of Odyssey: The Legend of Nemesis.
The game is exactly the same as it was when it shipped commercially
back in 1996, preserving the game in its "classic" 1996 state. Odyssey is a top-down RPG in the tradition of the early Ultima games, which on its release was praised for its rich story and unique moral system. Over time, Odyssey has become a cult favorite but has been unavailable for years. This version of the game is freely distributable and includes several bonus new documents, detailing the game's back-story and its development.
Classic and Mac OS X
Pretty much any Macintosh with System 7 or later.
