When I first started playing, it took me maybe . . . two months to grasp the "open world" concept. So I went around doing my normal JRPG business of talking to EVERY SINGLE NPC, which naturally ended up giving me a lot of sidequests . . . and I tried to finish them in the order in which I got them. And tried clearing every dungeon I found. And pretty much everything else. Because I had no idea how open world worked and I thought I had to. To make matters worse I didn't realize how the Quest Log worked, so I kept activating every one I got and ended up running mindlessly after the pointy triangle things until I found what I was looking for. Needless to say it took me a little longer than forever to finish Bleak Falls Barrow.
Oh, there was also a bit where I wasn't paying much attention to the game when Balgruuf told me to go to "the tallest mountain in Skyrim" (i.e. the Monahven) so I spent a good few days of real time trying to scale every mountain I could find that looked sort of tall-ish until I realized that the world map (among other things) existed. To this day I have no idea how I actually got up there the first time, since I kept trying to go straight up everything and went nowhere near Ivarstead.
Also I didn't figure out how healing spells, smithing, potions and things worked until probably after I beat the final boss, and just kept equipping the random stuff I picked up off the ground that looked okay-ish. And having near-death experiences with pretty much every boring bandit and wolf I ever met. And then waiting for like five minutes while my health regenerated at like one pixel every ten minutes or whatever it is.
Yeah, I have no idea how I survived this game, either :P
