Can't say iv read books on gaming, will definitely pick it up at some point.

I can't "reccomendt", but I'm planning to read "Metro 2033"

Bioshock: Rapture. It actually held up with the original story, provided some in-depth prequel deliciousness and fleshed out a lot of the characters. I loved it. Read it if you've played both games. There's even references to both Jack and Subject Delta.

Bioshock by John Shirley war really good.
Whole The Witcher series by Andrzej Sapkowski is well written.
WarCraft books were decent and so was Diablo
Mass Effect are worth reading, except the last one, that is garbage.

Good source for info about books is Goodreads

I thought the first Halo book was excellent. It was great in providing a backstory to Master Chief. The second was good, not great. Haven't read the rest.

READY PLAYER ONE - ERNEST CLINE

The only game-related books I've read are the Halo books and one of the StarCraft books. It's been ages since I read them so I don't remember much detail, but neither were very good. Between the two I'd say that the Halo books were more entertaining though.

The Witcher books are fucking amazing. I read them before the game actually came out and they are to this day one of my favourite book series. Though I think not all of them are translated in English

Though the game may have flopped horribly, I quite enjoyed the Hellgate London books. Well, the first one. The second one is ok, and the third one really isn't worth your time. But even with a story left open I would recommend the first one!

Just found my kindle so here are some more:
Alamut - Vladimir Bartol
The Myst Reader
The Infernal City - Grey Keyes
Portal Lab Rat - Ted Kosmatka

I'm in the midst of reading the New Jedi Order series, which is something like 20 books written by a range of authors. The first six books are pretty good, but the seventh by Greg Keyes is truly terrible and I'm struggling to get through it. Sadly, the eighth book is also written by that hack. Look up the timeline of books on Wikipedia to see where it fits.

Do read The Heir to the Empire trilogy, also known as the "Thrawn Trilogy". It takes place almost immediately after Return of the Jedi and does a fantastic job capturing the feel of the original movie trilogy.

Starcraft: Liberty's Crusade was incredible, it really expanded the Starcraft Universe for me and increased my interest in the games. Eventually I'll buy the rest of the books, but I'm not much of a reader so I have to wait until I'm in the mood :)

Metal Gear Solid 1,2 and 4 books..

Nobody mentioned Hitman: Enemy Within by William C. Dietz

This Gaming Life

A book of meta-commentary/travelogue/auto-biography/musings by one of my favourite game journos and founding member of RPS, Jim Rossignol. I haven't read the whole book, only excerpts, but those were very, very good.
