Oh. Um. They were just ideas. But what the heck.

Scavenger hunt. Provided with a list of ordinary, weird, dangerous, and silly objects to acquire before the deadline. Items might be awkward like a weather vane, dangerous like an expensive bottle of fermented Dwarven mine fungus, silly like a peacock feather from a famous exotic dancer, etc. A rival team could add extra spice.

Business advertisement is highly creative based on character personalities and the opposing forces such as the local security, rival businesses, oppositional forces like religious cult. This may take too much GM now that I write this.

Typical fantasy cities I don't think need much elaboration. I can pull something out in a few if you want. Like um Principality, court full of dandies and their much more dangerous wives, or whatever. Temple to the Goddess of Something on one end of the city and huge bulbous mass of stones the locals call the Prince's Bedroom on the other. Ten minutes or twenty to do it up. My brain oozes this stuff -- it's a defect of character.

Is that what you were looking for?
