Make some adventure ideas for Dungeons and Dragons (version 3.5), or other games (maybe some ideas can even be used in a roguelike game?).
Here is some:
- You find yourself in a completely different universe. In a few hours it reverts back to normal.
 - A wizard's time stop spell went awry and you now find yourself in someone else's body in the past.
 - A curse prevents people from walking in any direction other than straight N, NE, E, SE, S, SW, W, or NW.
 - You find a dungeon with a strange smell. It contains a artifact that duplicates itself.
 - Along the road, you encounter a kobold that looks injured, unconscious, bleeding slowly from an arrow wound.
 - You receive a letter from your dead wife (or parent).
 - Townsfolk are somehow being shrunk to six inches in height, and authorities can't figure out why
 - You have a magic item that you must figure out how to use in order to escape
 - Help an army of gnolls take back their city from a force of mindflayers.
 
Now you can make more to add to this list.
Also, I wrote a program in Furryscript to generate the adventure ideas from a list, look at:
