Legend
And some of those game inspired novels are modern classics.
Feist's 'Riftwar Saga' certainly is known to be and is one of the early examples.
As is Moon's 'The Deed of Paksenarrion'.
The whole 'Expanse' Saga by Abraham and Franck.
I can't prove it but Wood's 'Tales of the Ketty Jay' reads just like an Indy RPG.
Probably also Martin's 'Saga of Ice and Fire' (RPG meets 'War of the Roses')
Malazan Book of the Fallen started out as a GURPS campaign.
The Gentleman Bastard series started out as a homebrew WEG D6 game.
The aforementioned 'Craft Cycle'.
Probably more if I think about it or do some research.
