My first experience with the Elder Scrolls series was Morrowind. I will never get that entire summer I spent playing that game back, but I wouldn't want it back. I have such great memories of just exploring the map. It was my first experience with a world so big.
So for my pick of what's in ESO is Morrowind itself, I have my doubts that they would be able to do this though. If they can't do that, then I will take just a fleshed out world that rewards you for exploration with sweet loot, obscure quests, and samurai orcs alone on a mountain that just wants a warriors death.
