Overview:

Keep the check engine light off with MagnaFlow OEM Grade Federal/EPA Compliant Direct-Fit Catalytic Converter 21-172. With features including free-flowing mandrel-bent tubing and highly corrosion resistant, stainless steel construction, easily install this spun body converter yourself using the proper tools, no cutting or welding required. MagnaFlow's state-of-the-art metrology department uses the latest 3D scanning systems during research and development, so you can be confident that your new part will fit and function like the original equipment. By replicating the OE spun body design, the single laser fusion weld greatly reduces the possibility of a leak, and our compact, low-mass design also allows for greater thermal efficiency. This direct-fit catalytic converter is designed specifically for the 2009-2016 BMW Z4 and interchanges with OE part 18 30 7 647 051. The included gaskets & hardware reduce the possibility of a leaking seal while avoiding the need to reuse corroded factory parts for installation.

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.
