As the title suggests, I am thinking of returning to UO. I haven't played it in AGES, since the days of old. Yet, there is nothing out on the market right now that grabs my attention. The only game that I would bother playing right now is Vangaurd, but it is desolate. I usually find myself solo, dependening on free time, but I still enjoy an active community too. So.... is it worth the effort, and if so, what shard offers a fairly active community with RP, PvP and decent PvE?

Atlantic is always pretty active.

Atlantic has the highest amount of players right now. But I find Catskills to have a more active RP community.
