Don't Rest Your Head by Evil Hat had an interesting take on it. It's been a number of years, but if I recall you assembled your dice pool and where the dice came from had different colors, including some places where ti was voluntary to add or not. At the end it was the highest ... die? 2 dice? ... highest something, but where the dice came from affected the result. Like if it was from your Exhausted pool you gained another die to that pool, but if it ever had the most dice you fell asleep in the dream forever. Other ones might have changed the result, or drained a pool.
I forget the details, but it made assembling the dice you wanted to roll a balancing act between succeeding, and the bad effects of the optional dice you could add.
