#3 The Elder Scrolls Online
The Elder Scrolls Online is Bethesda's first ever foray into massively multiplayer online role-playing games (MMORPGs) and brings players into the world of Tamriel, the setting previously used in Skyrim, Oblivion, Morrowind, and Daggerfall before it.
Set a thousand years before the events of Skyrim, The Elder Scrolls Online will pit player against player within one of three major factions as the world itself is threatened by an ancient, evil daedric prince. Players must battle for dominance over Tamriel while simultaneously dealing with the demonic (or daedric) invasion.
What is it? It's an MMORPG akin to World of Warcraft and Guild Wars 2, but set in the Elder Scrolls setting.
