Good condition Amazing read.
Format: Paperback
Amazing book shipped in good condition which is surprising since it's a paper back and most my books I got from Amazon have at least a little damage from shipping. Definitely pick up this book if you make games.

My 22 year-old grandson was incredibly happy with this gift!
Format: Paperback
I can't write a meaningful review of the content of this book, because I don't begin to understand it, however, it was one of the things my grandson requested for his 22nd birthday, and he seemed thrilled to get it and he tells me it's a great book, so I can say whole heartedly, this is a terrific birthday gift for anyone who's into computer games.

More Theory than Actionable Advice on Game Design
Format: Paperback
Not a bad book, but not what I expected going in. I read this for a bookclub like event on twitch. I thought there was going to be actionable advice. Like 'do X to make Y feel". The introduction points out that the book is not about the emotional feelings a player receives from games, and this is true.
The book DOES provide a language for discussing game design at a more academic level. It is about the theory of how a game feels, and while I didn't agree with everything Steve wrote it was easy enough to follow the thoughts.
