I bought it for my two kids to read (if they are interested). I've had a quick read thru it and its a really good book.
If your interested in programming a 2D game using PureBasic then its well recommended. I used to program games professionally (back in the days when 2D was the norm) and if your a beginner you will have no problems with this book or following the examples.
The examples themselves have loads of comments and the style of writing is fun to read.
In my case the book was delayed being sent, so they sent me a free copy of Quill 3D to make up for it. nice

Anyhow, overall for the beginner or intermediate (who has never programmed a game) programmer I would give it 5/5 stars.
If your an advanced or intermediate programmer (who had programmed a game before) then its still worth buying, if not for picking holes in someone elses code or style

A good bonus for Fred is that the final example in the book (according to the note at the back cover) needs a FULL version of PureBasic to compile.
