This book was a rather good introduction to Common Lisp for newcomers. The games, mostly text-based or web+svg-based, are interesting and very well designed. Explanations are good, style is alright (well, I couldn't expect something to formal, could I?). I'm glad to have purchased it. However, it is not a very technical book. Those of you who want to go deeper should lean towards Practical Common Lisp.
This book was interesting to read through and has the right examples you need to build other programs.
I wanted to make a program with lisp that I could just write the channel that I wanted to watch on Twitch streaming service and it would do all the background work and load the stream through Livestreamer. As I went through the program, I was able to find the examples I needed to learn from and was able to build this program from scratch in about two weeks.
I would highly recommend this book who is interested in programming but has had sour experiences with other languages. I had 2 years of post-secondary education with c/c++ and I find this more enjoyable to work with.
