I think it's a good book, perhaps a bit "talkative" as it tells the history and theory of each game before code. That could be a bit boring for those who really just want to get on with it.
The python code itself is simple to follow, assets are included and not half-bad too.
I'd say this is a decent start for someone who has passion about games, a little coding experience and serious about getting making one themselves.
Whereas I feel like you can learn to make games from any number of sources, but learning the history is what makes this book special. Different strokes for different folks.
This has some pretty nifty stuff in it (not to mention all the cool interviews) but my favourite part is them describing the sensible soccer clone AI as that's one of the trickiest things to get right in gaming.
