Playing Resistance /resistencia is such a great way to practice the subjunctive and the imperative in Spanish.
It is a very fun game and uses bucket loads full of subjunctive phrasing. I think it's a game that people will want to play over and over again. The game is played with a minimum of 5 people or maximum of 20 people.
It is easy to find at any good game store.
This 8 page lesson includes such of the basic phrases to use for the game, a brief description of the imperative and subjunctive (which should both be taught side by side anyway) and some examples of the vocabulary from the web.
