#RPGaDay, Day 9: Favorite Tie-in

I think the only novel or game fiction I ever read which was a tie-in to an RPG (where the RPG came first) was the Forgotten Realms novels with the infamous drow ranger Drizzt in them.  They were readable enough but I've read a lot more fiction which later became a game:

• Elric
• Dragonlance
• Call of Cthulhu
• The Dying Earth
• The Gaean Reach

(Not surprisingly, the last two are from novels by my favorite author, Jack Vance.)
