Okay - as far as plot elements. As I stated in my very first post, I really enjoy character development. I would personally like an adventure that not only helps each player get into character (Duh, that's kinda the hope for all games, right?) but also one that encourages party cooperation. Not that we aren't going to have our disagreements, but an adventure that relies at some point on each of our talents would be cool.
As for specific goals, the old standbys are always good: Hunt down the evil mage/psion, find a minor lost artifact, slay the low-level werewolf, and everyone's favorite - withstand the undead horde!

But any of those would be cool from my perspective. Other thoughts?
