In The Elder Scrolls Online for the PS4; Most of the continent of Tamriel is available in the game, although much of it is locked off for expansion content. Players have the opportunity to join any of the three factions warring over the throne of the Emperor of Tamriel: the First Aldmeri Dominion, composed of the Altmer, Bosmer, and Khajiit races; the Daggerfall Covenant, composed of the Bretons, Redguard, and Orsimer; and the Ebonheart Pact, composed of the Nord, Dunmer, and Argonian races. Players may also unlock an additional race, Imperial, which may be a part of any of the three factions. Pre-ordered copies of the game included the "Explorers' Pack", which allowed all races to be played in each of the factions.
The Elder Scrolls Online had been in development for 7 years. It is the first project for ZeniMax Online Studios. Matt Firor, studio lead at ZeniMax Online, is also the director of The Elder Scrolls Online. While rumors of a massively multiplayer The Elder Scrolls game had been circulating for years, accurate information about the game and its imminent May 2012 announcement was not leaked until March 2012, to online publication Tom's Guide by an anonymous industry source. Bethesda spoke about development of the console editions, announcing that the release date for the PS4 version of the game would be delayed until the end of 2014, though it was revealed that the game's console debut was once again delayed into the Spring of 2015
The Elder Scrolls Online has received mostly mixed reviews; the game has a weighted aggregate rating of 70.93% on GameRankings, based on 46 reviews, and 71/100 on Metacritic, based on 63 reviews. The game was mainly criticized for an excess of bugs, a phasing mechanic that separated players from groups, and its Veteran Progression System. Zenimax has responded to these criticisms by fixing many bugged quests, introducing a new phasing mechanic that did not separate groups, and is currently working on a replacement for its Veteran System called the Champion System, scheduled for completion later in 2015.
