Ultima I

A 1986 assembly-language remake of the original 1981 Ultima, featuring improved graphics and minor content additions. Players explore the open world of Sosaria in a top-down view, descend into first-person dungeons, complete quests for the realm's lords, and engage in space combat, all in pursuit of the immortal wizard Mondain and his Gem of Immortality.

A thousand years ago, the wizard Mondain forged a gem that rendered him immortal and beyond defeat. Under his protection, monsters overran the realm of Sosaria while its lords fell to infighting. Lord British calls upon a hero from another world, known only as The Stranger, to locate a time machine, journey to the age before the gem existed, and slay Mondain before his power can take root.
