Although I don't entirely disagree with people calling for a wilderness sandbox, I think there's something to be said for a more urban, investigative adventure too. I remember a rather good one from Dragon magazine, set in Specularum, Nests and Nations I think was the name. Lots of plotting, investigation, deal-making with different groups, and a few fights. Quite a long adventure too, took us several sessions to play and we didn't meet all the groups involved. See how/whether the rules can handle something a bit different.
