Similar gamebooks to mine

My story idea is a fantasy adventure, with knights/dragons/warriors etc
I've looked for gamebooks similar to mine and I found a series called Wizards Warriors & You

'The books were invariably set in Medieval England, which was ruled by King Henry. They all starred a nameless Wizard and Warrior, and began with the reader choosing which of the two characters (s)he would "play", with the other character providing a supporting role. At the back of the book the reader would find individual inventories for the characters: The Book of Spells for the Wizard, The Book of Weapons for the Warrior. The two characters' paths through the book were independent of one another, diverging after the introduction, and only reconverging at the end' 

1. The Forest of Twisted Dreams (1984)
