It is notable that originally, the game was going to include an artificial life engine that "would affect animal behavior, potentially creating new adventure possibilities in an organic manner." But it never made it past beta development as, "We thought it was fantastic. We'd spent an enormous amount of time and effort on it. But what happened was all the players went in and just killed everything; so fast that the game couldn't spawn them fast enough to make the simulation even begin. And so, this thing that we'd spent all this time on, literally no-one ever noticed – ever – and we eventually just ripped it out of the game, you know, with some sadness."
One of the games more memorable events occurred in it's beta in which the in-game alter-ego of Garriot, Lord British, was successfully killed by a player character. Lord British was supposed to be invulnerable to this kind of attack, but a server crash had made him vulnerable. This event is considered by some to be the most memorable event in early MMO history, and led to the saying "If it exists as a living creature in an MMORPG, someone, somewhere, will try to kill it."
Ultima Online still active. To celebrate their twentieth anniversary, they had a real-life party in Herndon, Virginia, near Washington DC. They also have a new content arc, "The Shattered Obelisk." So after twenty years, presumably with some of it's original players still at it and some new ones who weren't even born yet when it first came around, "UO" is still offering players the chance to do some monster clobbering and dungeonering.
