No, the game, especially in the field of training, is not a fad or a lit dream: it is effective and the results are there! I have not tested all proposed framework games, but the 3 experiments have actually changed my vision and give another dimension to my classes. My listeners were surprised, but for them also, the experience was successful and they want more! This book is made very practical way. Each game is set in context and explained. A third party can address variations or respond to most problems. The games do not necessarily require a lot of preparation, making them even more attractive.
