Once the greatest game of all time. Then AOS (Age of Shadows) was released and the game went down hill then and every year after.

Was a great game to grief and harrass other players. Now full of trammy noobs who are all worried about rares.
I made over $5000 on an Ultima Online player ran shard. I won UO more than once.

Fun game for the first few months after that its pretty boring but you just cant stop playing!

Do not pay monthly for ultima!!! play the free versions!!! age of shadows sucks! I say go with UOR or even better pre UOR.
Ultima Online is a very addicting game

I play Defiance free shard.
