To add to the 'quest' discussion: I was happy when they mentioned (in the new interview video) the reason why they cut down on the amount of Guilds: to provide more personality to the characters and add more to the Guilds' storylines. I really am hoping the quest givers are truly interesting and that there is a variety of them.
And the quests better be more...interesting!
And the quests better have much more worthy rewards in Oblivion!

If there's one thing I hated in Morrowind, it's that sometimes when I finish a difficult quest/task, some NPC's give no reward! :confused:
EDIT: Thank you, guys, for the awesome interview! Um, I assume the guy in the video was Alexander, right? Well, whoever you are, :goodjob:!
