Those Res books are alright just don't get 2 or 4 cause they are beyond shite ! the Uncharted books quite good as well.
As for other gamin novels well the obvious ones are the halo books. Iv got contact harvest , fall of reach , the flood , first strike , ghosts of onyx , Glasslands and the Thursday war ( the last three are properly good ! ) there's also the cole protocol and the forerunner trilogy but those I haven't got so I can't say whether their any good or not.
That's all the ones that I have but there's loads more out there. I know there some for Dues ex , command and conquer , dead space that expand the fiction and ones for god of war And metel gear that are straight up books of the games I believe .
Not a novel based on a game but it is a novel about gaming is ready player one , put of every thing that iv said that is the one I'd recommend above all the others cause its fantastic !
EDIT- Bastard I just noticed what Mag wrote and I'm the boring sod it seems
ah well I'll go back to reading my stargate books now...............
