I'd never written a game, so thought I would try something as simple as possible just to start to understand how it is done. It just so happened that the Running of the Bulls was on in Spain the following week, so there you have the theme. If you don't know what the running of the bulls is, it's a stupid event where crowds of people, including lots of drunk tourists, harass bulls and then kill them once the event is over.
As someone who believes passionately in animal liberation, the fact that I have never gotten around to reading the ground breaking Animal Liberation by Peter Singer, was only due to slackness.
To make up for this, and to get a feel for Singers other writings, I bought this book for a bargain price and proceeded to read.
