Are you teaching them the game also? Kids these days are inundated with a thousand directions that they should go. If a setting that is offering some of their favorites, music, food, atmosphere for socializing, is set up then the competition aspect can be offered too. Give them a good place to be when they're looking for a good time and then let them find this game that is a given for a way to express themselves competitively. The soda fountain days of the 50's would have been a prime place for foosball should it have been available at the time. Where can these kids go today that is for them?
