I'm a huge morrowind fan, but the reason I liked it had nothing to do with the fact it was based in Vvardenfell. I loved that game for the freedom and how much work they put into making it.
For those of you who don't know, Zenimax was going to close Bathesda down. So Todd Howard went to them and said that if they give him the budget, he will make them one of the most amazing games they had ever seen, and they said... sure Todd, why not.
Bathesda put there heart and soul into making that game because it was there last chance to keep building games. THAT is what helped make that game so unbelievable. ESO could never deliver that same experience. Not to say it's going to be a bad expansion, because I think alot of people will enjoy it... I just don't like the gameplay or overall experience that ESO has to offer.
Ill probably just wait for Skywind.
