It also has classes, standard lvl up system (so no Skill based system TES is known for).
Morrowind and Oblivion had classes as well, and the ability to make your own. And the fine folks in Germany who made Nehrim experimented with a standard lvl up system for Oblivion. It was OK-ish I guess.
All right, I more concerned on combat, personally, but if you insist. The 3 factions are:
Aldmeri Dominion
Ebonheart Pact
Daggerfall Covenant
Aldmeri Dominion? Isn't that a name that only comes to exist a 1000 years later?
