Renaissance adds more options for players, creating a duplicate world under different rules. So Fellucca and Trammel were created, the first one with "player vs. player killing" allowed, and the second without it. In game terms many considered this a breaking factor. Some argued that this was the end of traditional, realism-oriented UO, others saying this should have been done earlier because not everyone enjoys PvP combat.
By 2000, many prospective players considered Ultima Online dated, despite the efforts of updates and expansions such as Renaissance. The influx of fully 3D MMORPGs such as EverQuest (1999) started to impact the commercial growth of UO. The game has not seen significant increases in its number of subscriptions in years. Fans of UO sometimes note that UO was the first highly successful MMORPG and that Renaissance was its first reaction to a competitive market.
