To answer your question about comparing ESO to other MMOs: ESO is not really a traditional MMO, so we don’t use that term much around the office – and it is this distinction that separates it from other games. If you want to play it solo, like you did with other Elder Scrolls games, you can do that. If you want to play it super-grindy with dungeons, Trials, and group bosses as the core of you experience, you can join up with others and do that too.
It’s really up to you to figure out how you want to play it, as we don’t enforce a play style one way or the other. In fact, ESO has been super-successful at taking gamers not used to massive online games, introducing them to the concepts of group play by making it fun and optional, and turning them into online gamers.
I think we could have done a couple of things better at launch like setting proper expectations for our betas (which for the first few were done primarily for technical scaling testing, not for game testing), and we definitely launched with a content bug that prevented many players from completing quests.
