A combination of Historical, Sword and Sorcery, his Bard series (5 books) is an enjoyable take on the bard of history and the bard of more popular fancy. I don't know if he is a gamer, but the series is wonderful inspiration for gamers. I can recommend the first three books in the series. I stopped reading somewhere shortly after starting book 4 (and can't remember why) and only recently picked up book 5.
 
He has a long list of short stories but the work is a bit too recent for me (I've never read any of the newer Weird Tales magazines or caught the work he did in the 70's).
