So equal first: the game is awesome and is always fun! Earlier you played it with homemade labels and variations, today there are so to buy the cards. I find it quite nice - except for the fact that the maps only symbols or images and then you just have to know which character is shown. that is with new players, of course, a bit difficult, because first must be declared (naturally without the other what mitkriegen). That's why I give a point deduction.
Whether you should buy the cards at all or whether the "old version" is not enough, everyone must decide for themselves ;-)
