Ultima V: Warriors of Destiny

Ultima 5: Warriors of Destiny is a computer role-playing video game published in 1988 by Origin Systems for the MS-DOS operating system.

Since MS-DOS was discontinued in 2000, Origin Sys. was disbanded in 2004, and the copyrights of the Ultima series and the Ultima characters belong to two different owners, all this makes Ultima 5 de facto abandonware (remember that de facto means "in practice or actuality, but not officially established").
