Why not just play on an established server?

This is harder than you think. You cannot just open up a server and expect to draw many people. Even long time servers like Angel's Island have minimal population (<100). It's really not fun to play without a decent pop.

I would suggest just playing UO Hybrid if you want your UO fix. One of the largest populations out there and it's easy to get 'into the game'. There is no anti movement there and lots of pks so we would be needed. I own a keep on that server too if you need to place to crash.

I just see a new server as a costly way of reinventing the wheel.
