Comment Custom shards saved that game (Score 4, Informative) 75
A good shard (UO-speak for a custom server) would have great GMs regularly creating events for their players. I've played through a week-long monster invasion on Minoc, a war between Trinsic and Yew, a murder mystery involving 100+ players, and more custom "dungeon" areas than I can count. The last dungeon I remember was a play on Alice in Wonderland.
I haven't played UO in about 10 years, but custom shards gave hands down the best MMO experience I've ever seen even compared to current games.
