Prior to getting back into the indie/homebrew/hack mode of thinking, my gaming group was heavy into Paranoia. Specifically, they loved the concept of a group of Troubleshooters working together on the surface, but repeatedly and hilariously backstabbing each other the whole time.
I've been trying to come up with a good system to facilitate inter-party backstabbing and have been coming up with blank. Currently, the players either write down their intentions on a slip of paper and pass it across the table, or send me a text message with their backstabby ideas. This works okay, but I often find it difficult to manage all these different ideas from six different players.
Does anyone have any keen ideas on how to help facilitate secret backstabbing?
