Last night I played Dixit with my family and my brother's family. Of course, my brother immediately tried to "break the game" by using clues that he thought only his wife and/or kids would get. Some clues were the names of their family friends. While this plan backfired in a spectacular fashion, my question is this: In Dixit can the story teller use clues that are proper names of non-celebrity people (liker personal friends), or foreign words knowing that only one other person speaks that foreign language? I can't see anything in the rules to stops this, but it sounds like it could be abused. What do you think?
