Best Elder Scrolls game? Yes and no.
Combat. Yes. More visceral, precise and third person is better than ever.
Questing System. Worst. I miss actually searching for stuff instead of being handheld to it. Turning off compass goes a long way. But you cannot turn off everything as journal doesn't offer sufficient information anymore.
Dialogue. Best voice acting. But too few choices anymore.
Its an awesome game, with loads of play value, but its not without its issues. Some of these issues are critical. And some of these issues rear their ugly head in every installment of the series. Bethesda need to solve these someday, because it cannot keep up.
