Music, background music or sounds while playing! Why not?! If it makes some of the players happy. Then, if one day MadWin decides to enhance his games with sounds, in this case leave the choice to each player to activate them or not. Everyone will be happy!
No, but it would be more fun. During the month of December 2008, there was the "express fir tree" game and there were sounds (and even music I think), it's true that some sound for the games would be a good idea.
