Muliplayer only possible with multiple DS cards

A fun game, but for younger kids but also quite difficult to pass the tasks. Unfortunately, you can play the game in multiplayer mode only with others who also have the Playground DS card. That was very annoying. Since the Games would otherwise be even more fun. Ansonten we like that here good responsiveness is not only required, but also memory and tactics for the game winning the small games. Furthermore, there are different levels to which you only get when you've made the first hurdles. The texts are in German and the graphics are also ok.
