I have long been an advocate of teaching through games, whether in the form of role play (such as are called Strike!), simulation (Stockpiler) or computer-based. When I was teaching Econnures I realised that I could have taught quite a chunk of the synabus if I'd been able to run Sim City on the school network, but I had neither the budget now the hardware to make that a possibility,
The value of this book is that it explains why some games help students learn. Even if you don't have the games referred to (not on a which require a computer anyway) you could pubably find some you could use instead.
However, although the book is interesting and explains things well, I'm not fully confident in recommending it. It's twenty years old, games have moved on since then, and there doesn't appear to be a more recent edition. If you come across a relatively inexpensive used version it might be worth a modest investment though.
