DB Favourite moment : a very unprecise one, but it was a mix of roaming through the ashland with a revamped music of morrowind in the background! It felt like I was rediscovering the game, it was so so epic the music reminds me of certain MMOs for some reason and the tunes are lively!
Least favourite moment : the end which I was not waiting for in the sense that it came upon me much too early. I felt the main quest was too short and I didn't connect much with Miraak who, in the end, was a rather forgettable villain, in my opinion of course (although his outfit is great looking)
DG Favourite moment : that one's a no-brainer : entering the Forgotten Vale for the First Time with the music theme in the background!
Least favourite :
Spoiler
Having to choose the Dawnguard just for crafting crossbows and bolts(I need this since my build is a ranger). It was heartbreaking when I had to clear out Castle Volkihar of all those Vampire guild members who looked really bad !!
