Played the whole weekend of the beta, loved it. But there's basically 2 things that are keeping me away of buying and playing it.
It's an MMO. Yes, I said it. The game is ruined for me since it's an MMO.
Not that it's just an MMO, but that it didn't feel like an MMO. There was no real reward for playing with other people, the "dungeons" were extremely dull and just messy because the nonexistent agro except for my taunt. The game was much more fun when you started playing it like a single-player game, exploring and doing quests just on your own.
It's pretty much so that MMO and Elder Scrolls don't fit together, in Elder Scrolls immersion and some minor RP possibly have been what made the games so excellent, in ESO it's just like a single-player except that there are just random people jumping around and breaking any immersion you could have. (And the chat, oh my god. The amount of whining, foreign language, bad grammar and trolling/flaming forced me to close the chat, leaving the "chatty part" of an MMO hidden as well)
I hope that Bethesda is already working on the 6th single-player Elder Scrolls game, there is no Elder Scrolls experience here for the true fans, and is going to be a bummer for many, not all, but many Elder Scrolls fans.
The lack of open beta is weird as well, I'm lucky I got to the weekend beta as I would've never have paid 60 euros just to see if the game is good. Since the reviewers had it all wrong as they played the game for pretty much an hour which is way too little for this game, can't be trusted to give a give a good review.
Edit: This didn't turn out as "short and sweet" as I expected
