The goals are clear, but there's always something that goes wrong to mess it all up, and Vampirism is pretty easy to get. In three of the Guilds, I had to deal with Vampires. Two of them got me infected, one of which I cured right away, and I got it in the last one.
It's like, Bethesda wanted you to get Vampirism at some point in the game to give you something else to do, or make you change the way you play by staying a Vampire. If you don't want it though, it's a real pain in the neck. Hardy har har!
I figure each of the quest lines of each Guild takes about five hours or so. There's four Guilds, so that's 20 hours. Then there's the main quest which I'll start after doing the Thieves Guild. The guide I'm using says you can do all the major quest lines and the DLC in 25 hours. With all my screw ups, I'm probably gonna spend about 35 after all is done. So, it's not that long really if you stick to the main quest lines. There's a lot of side quests that net you experience or special items. I'm not doing any of those this time around.
