How did you beat the main quest that fast? o.o
In all honesty (not bashing this or TES) oblivion and skyrim is just a little lacking on a lengthy main quest. But that's not how i beat it so fast, it just contributes to it. But its okay cause even with fast travel and power gaming i clocked in 80 hours on that char. the Side quests are just so numerous.
I used fast travel and that is essentially how you beat it so fast. Take out fast travel and im sure it would take around 3-4 hours to beat if you did nothing else.
That sair on my second, legit character im doing pretty much all of the "monotonous" randomluly generated quests and throwing in some actual quests as a supplement just so i can hit 50 and have loads of fun when leveling slows down.
