However, that's not to say that Bethesda hasn't done a fantastic job with quests overall. It's strange, but the miscellaneous quests often leave me feeling like I've really done a favor for someone. Sometimes the rewards for the radiant, miscellaneous quests are even better than some of the main questline rewards. Indeed, even in the guilds each individual quest seems very genuine, and makes the player feel rather helpful. I was quite excited when I went on the first College quest, I felt like a legitimate student on a real adventure with my professor. On the small scale, everything is fantastic.
The Daedric quests in particular... there are just no words. They're incredible. I don't want to give away any details, but they are so dark, and can often creep up on you. You don't neccesarily start them just by showing up at their shrine and asking if they need any help, like previous games. No, often you get roped into something that looks like an ordinary quest, and then you find out halfway through that you've been hoodwinked into this sadistic, horrifying series of events that, should you go through with it, you get an incredible reward.
I have to say, I love this. I don't know how it is that Bethesda manages to be such a dichotomy with itself, but they do. The pendulum goes back and forth, too. In some games, their guilds are just fascinating, deep, and very fulfilling to complete (Morrowind) while the Misc. quests just seem half-hearted and mundane. The opposite is true in the case of Skyrim.
So that's my 2 cents. For all the moaning I do over how very unsatisfying the main quest lines are, I find the miscellaneous ones to be incredibly engaging. So... for whatever that is worth, I like it.
