The thing, apart from freakin' bugs in Skyrim though was I never felt I had to micro manage quests. The quests were more linear in regard to difficulty, as you levelled the quest kept pace, more or less. You could wander into an area that was way too difficult but in general quests were balanced. I love the Witcher series but I never felt, playing the previous games, pressured into managing them the way I do in this game.
in general I feel the quests aren't balanced to the player, I keep thinking I have to do these low level quests otherwise they aren't going to be worth doing. If I have to set the game on the highest difficulty in order to be challenged then there's something wrong in the quest progression difficulty. That's just my opinion though, don't flame me for expressing it.
