http://www.raphkoster.com/tag/ultima-online/ has a bunch of blog posts from Raph "Designer Dragon" Koster, one of the original designers of UO. It's amazing to read about how "world like" the original game was, especially compared to the direction that EQ/WoW took the genre.

Raph Koster is now one of the founders of a company developing a new MMO, Crowfall. The devs claim it will take a lot of inspiration from UO.
