One of my players (Hi Rolando!) recently mentioned the Fiasco-based character relationship system we created for a D&D campaign in a letter he wrote in to the Metagamers Anonymous podcast. I thought I'd post it so listeners could see what we did.
Fiasco Style Setup - Life After Giants
4 dice per player. Take turns picking up a die and using it to declare something.
Between each pair of players there will be a Relationship. That relationship gets a detail.
