Skyrim has two questlines. The main quest, and the side quest. The main quest is what it is, and the side quest they just duplicated 5-6 times, changed character/faction names and tricked everyone into thinking the game had an obscene amount of quests. Honestly, if you get 10 hours into this game without realizing you're doing the same fetch quests over and over, just for different people, you lack many brain cells.
