Having no experience with MMOs, I can say I enjoyed it. I don't have anything to compare it to, so I just take it as it is. The combat system doesn't feel as good as Skyrim, but I really wouldn't expect it to. Single player games will always have an advantage in that regard. Once I got a few abilities, I found myself really liking being a mage. I created a young Hal-Neesa. She was born in the second era, after all.
Also, I posted. I'm done with ESO for now, as the last beta is ending within the hour.
