With games of this type (Skyrim, Fallout3, Assins Creed etc.) I always like to do as many of the side-and other quests first before continuing the main quest-line. I've been playing a Nord warrior for about 2 weeks now, doing the quests not in any particular order. Sometimes switching from Thief Guild quest to Dark Brotherhood or mage stuff and then back to some of the "radiant" or miscellaneous quests. One thing that really bothers me is that the quest menu does not indicate which quest is a main storyline quest. I wish there would have been some indication I was doing Act 1, 2 or 3. Only by checking the walk-through or the Wiki did I now realize I am only 3 quests away from the end of the game, but my character is only level 38. To me that just really sucks. The only other option I have now is to abandon the main quest line, keep checking the wiki so that I don't accidentally continue it, and keep doing other stuff to develop my char and increase the perks. *end rant*
