5.0 out of 5 stars
good stuff, 30 July 2012
Ordered this for my portal-obsessed son and it was an extremely popular hit. Obviously it's missing any of the dlc that came after initial publication (such a the new level builder) but the interviews with the folks from valve are a fascinating read.
There aren't many games where this kind of book would seem worthwhile, in my opinion, but portal 2 is one of those exceptional few whose originality make it work.
