I really enjoyed using this website. I spent about half an hour on the site playing with the interactive game as well as reading some of the text explaining the whole concept of the Prisoner's Dilema. This website introduced me to a concept in Philosophy that I had not been exposed to yet-- Game Theory. I found the concept fascinating and it would have been extremely difficult to understand without the aid of the interactive game or the easy-to-read explaination. I would almost certainly use this in the classroom in a course which covered this material. The website as a whole is very user-friendly. The page is well laid out and pertinent to the field.
