UOGamers is the shard setup by the RunUO team. They used it for introducing features to the EMU. Plus since its their shard they have th emost users. Naturally. But they have 4 shards. Rebirth (Pre-T2A / Pre-R) , Hybrid(UOR), Demise(AOS/SE), and Aftermath(Havnt played it yet). Which is quite funny considering AOS and SE was the demise of UO completely. With the release of ren it was getting there =/
