I have been thinking about a similar problem but couldn't find a nice solution for it, and I feel like the conversation game is a pretty good idea. The original problem I was trying to tackle is how to make people realize the cognitive biases that we filter our thoughts through both consciously and subconsciously, and how it is distorting our view of the world and allowing us to be manipulated more easily than we know.
I am upvoting and reblogging and if there is a developer out there interested, I am a UX designer would like to offer my services as well.
