Ultima Online,known as UO. We made a server that is era accurate before the very cheesy Age of Shadows expansion. The server is designed mostly for pvp and pvp rp, the pve isn't bad either, its really an awesome job we did on the game, hard to explain, send me a message on our AIM sinsomnia pub16 and I can answer all your questions, and give more details as I'm trying to keep the post concise.It's completely free to play and 90% of all donation money goes right back into the server for scripts, maitenance, server rental, and advertisements.
