Ultima IV - Quest of the Avatar

About Ultima IV - Quest of the Avatar

Ultima IV - Quest of the Avatar (1985) is the fourth game in the iconic Ultima series. As the first game in the Age of Enlightenment trilogy, it marks a radical departure from the kill-the-villain formula and the Tolkien/AD&D influence of its predecessors.

Since Ultima III, the world previously known as Sosaria has undergone massive geographical changes and is now united under the leadership of Lord British and the name of Britannia. There is no single great evil threatening the world, but the people of Britannia need an example of morality to follow in their day-to-day lives. Ultima IV introduces ethics to RPGs in the form of a system of virtues. The player must master the eight virtues through righteous behaviour and ultimately become the Avatar.
