What do your dice say about you?
Now the dice themselves obviously speak volumes just by the sheet number he has. I see several sets of dice represented along with a variety of oddballs. This gamer wants to be prepared for any situation but I bet that he has his favorite dice that he picks out each time to use over and over again (notice the red and clear dice set to the side). I'd imagine this gamer is loyal to his friends as well - both in and out of the game.
Look for this player to say, "I'm going to get another one... anyone else want one?"
