Vast and Exciting
The voice overs are a lot better then prior games of the series but still no where near where it should be for a major US release.
The number of quests in areas and how those quests are organized is a low better then another big free-form RGP I can think of where you end up following the compass indicator around all the time to find quest objectives.
I look forward to seeing what the endgame has in store and think that I will enjoy the ride!
