This one is actually lifted in equal parts from the dating site OKCupid and a conversation I had last night. OKC matches people up based on a huge database of questions; the more you answer, the more confidence the site has in the matching. The interesting part is that the questions ask how you would answer, and how your ideal mate would answer. IIRC, there is a way to check "reflexive incompatibilities," where you answered in a way that you wouldn't find acceptable for your ideal mate to answer.
Question: If you were cloned five times, and your five clones sat down to play a roleplaying game, what would work well and what wouldn't? What sorts of reflexive incompatibilities would show themselves under these conditions?
I think one of mine is that my clones would get frustrated with each other for not being active enough. That probably means that I expect more of other players than I hold myself to in this department.
