I saw he did a box art version for the n64 one too and I ordered it through amazon, was there one for the PlayStation as well?
Unfortunately, the English PS version didn't have a separate box art book. There's also a 3 volume French version, but I'm not sure if that has all the box art either. Here's a comment from Kickstarter explaining the differences:
The difference between this version and the trilogy is a very simple, yet very big change. In this book, it appears to only have the interviews and history of the PlayStation, in chronological order. This would be OK in a vacuum.
However, the trilogy did things a lot differently. The trilogy was a chronological recount of the history of the PlayStation as well, but at the end of each volume, there would be reviews for almost every game on the PlayStation, with each book covering a specific timespan of the system.
Book 1 did every game from 1994 to 1997.
Book 2 did every game in 1998 & 1999.
Book 3 did every game from 2000 to 2006.
This was the biggest reason I wanted the books in English. The database of games with English blurbs would have been an invaluable resource whenever I decided to go treasure hunting in the PlayStation library, but with this only being one volume and only having the interviews, I don't really want the book anymore, especially after the effort that was made in translating the N64 anthology in it's completion.
I chipped in 5 euro anyway, because I do believe these guys do good work, but I can't avoid the fact that I am extremely disappointed.
