I just bought some books from Amazon UK:
Supercade: A Visual History of the Videogame Age 1971-1984
The Ultimate History of Video Games
Guinness World Records Gamer's Edition 2010
Rogue Leaders: The Story of Lucasarts
Arcade Mania: The Turbo-Charged World of Japan's Game Centers
Vintage Games: An Insider Look at the History of Grand Theft Auto, Super Mario, and the Most Influential Games of All Time: An Insider Look at the ... and the Most Influential Games of All Time
and a DVD of The King of Kong, for only GBP 4 (I lost the original copy of my backup somehow

)
So I have will have some nice stuff to read soon, but I saw in the replies above some other must have books. Unfortunately they were not in the listings of Amazon UK.
