I learnt programming from running an ultimate online server back in the day. A little sad to seeing an(I assume), open source server like this being taken down. As an admin we use to run on the premise of, if we weren't told not to run it, we could. Probably not 100% legal but it seemed to work. It does make me wonder if they take the server down, is it because their subscription dropping so much?
Did you mean Ultima Online? Loved that game, were you running a sphere or RunUO server?
Yup, ultimate online, on runuo. Had a fun few years there.
