Never a game had so much detail in its making.
Another thing to point out is that the side quests are very immersible and i have found my self fixating on them instead on continuing on the main story, which so far has seemed to a lot better than previous Bethesda games, although its the usual "someone/something evil has came back to destroy the world" type of thing . Another aspect that makes it so immersible is the soundtrack, every time i start the game up i leave it on there for a few minutes to hear the main theme. The music that plays when walking round villages somewhat reminds me of the theme to "Game of Thrones" and cannot stop myself from humming a long, the dramatic music playing when fighting a dragon or when you've leveled up fits perfectly into the game and what helps make it the masterpiece it is. Also the interface is very user friends and is easy to find what you're looking for and doesn't take you away from the game. My only complaints in the game would be the map, although seeing a 3d world is very cool, its hard to see which roads to take as they don't show up too well. as well every now and them when when people are talking in a group people may walk past and try talking to you which stops you from hearing whats going on at time. At the end of it these two problems are not game breaking and can easily be forgotten about.
