I have very fond memories of Ultima 6. It was the first RPG game I played that had a real depth. Many feature were groundbreaking for its time, such as the daily and nightly schedules for the NPCs, the non-linear storyline and enormous freedom you had in exploring the world. The plot was very well written, dealing with a powerful culture clash between two races, humans and gargoyles. The gargoyles started out as a seemingly stereotyped enemy, but actually turned out to be a very evolved and intelligent race fighting for their survival, and that you had to befriend in order to reach the common goal: peace. A stunning work of art created by Richard Garriott, Warren Spector and Dr. Cat.
