In the realm of Sosaria, a land divided by a thousand years of agony brought about by the malevolent sorcerer Mondain, a lone hero capable of turning back the tides of darkness has finally emerged. That hero is you. Your mission, a slight variation on the standard kill-the-evil-wizard theme, is to assemble a time machine, go back in time before the evil wizard developed unstoppable power and, then, of course, eliminate him. Ultima I is a remake of the classic RPG Ultima from 1981. The game features tile based top-down overworld graphics and first person perspective pseudo-3D dungeons. The original Ultima was re-programmed using assembly language, with updated graphics, minor changes in towns' and people's names, and some different puzzles.
