you might be goin through this game a little fast but its to late now, ecspcially since it sounds like its ur first time playing.

People play at their own pace which gives them the most exciting time, it is just a game afterall.

He probably has something he wants to do in mind, like getting through the plot so he can concentrate on doing all quest next time he plays, or something like that.

Well, I've been first completing a whole lot of quests before I went to chapter 4. Well, execept for 2 I know are left: the slaying of Firkeep, which I postpone till I got a stronger party, and the quarreling families in Trademeet, about which I can't make up my mind. Big chance there are quite som left, but I didn't come accross them yet. Maybe because I have basically the same party from the beginning?
I'm now somewher on day 120 or so in the game.
