well, i played various RPGs so i got most of my fantasy stuff from there; Call Of Cthulhu and Gamma World were really big, for me.
But as for books, i LOVED a Heinlein book called Glory Road. Swashbuckling adventures .. kinda.
And in the same vein, but even funnier .. Another Fine Myth, by Robert Asprin. This is actually a cycle, but only the first 3-4 books were funny, it kinda got forced and repetitive after that.
"Fafhrd and the Gray Mouser"
with all due respect to your own taste, this is maybe the series i hated the most. half of it is rape, half is ridiculous scenarios that dont make sense to anyone over the age of 12.
"grey mouser is attacked by an earth elemental, who
buries him. (literally buries the fucker alive) but mouser is so cool, he says fuck it and breathes by anaerobic respiration".
because if you are ever buried alive, just stop breathing and this will prevent you from dying.
im not making this shit up. this is actually a scene in a major mouser book.
