I've been threatening to write it down for too long now, so I finally wrote down how to play Fiasco with ordinary playing cards instead of dice. I call it Fiasco Poker. I've been meaning to use it alongside a playset, but I still haven't written that yet. I also think it could use playing card-specific Turn and Aftermath tables, but I haven't even started on that either.
Feedback is welcome. I hope it makes for fun sessions for everyone that is willing to try it.
