It's a game about guessing what your friend, the reader, thinks about the card they read? Sounds kinda interesting. Of course, it could also be boring if played with someone you didn't know very well (or someone you didn't care to know very well.
I was worried about this as well! Funny thing is, when I did play tests with people who knew each other well...they actually started lying about their true feelings in order to trick the other players into guessing wrong.
