Apples to Apples is one of the greatest family games ever. I used to work in a game store and was demoing it to this lady. I put down 'kinky', the match she put down was 'chains'.
Apples to Apples is the envy of the gaming industry now. It has already surpassed 1,000,000 units sold. That doesn't happen with [censored] games except Monopoly.
Quiddler is a card based word game. Very fun and a MENSA Select game.
