This person isn't just a GM; they're a roleplay partner, in the truest sense. If you like having lots of freedom in how the story and setting is set, AND if you like having someone to give you ideas and brainstorm with you, THIS is the GM for you. And even if you don't, this GM is marvelous at crafting any world and story you would like to play within. I have never had so much creative freedom before, and never have I had someone appreciate my ideas the way this GM does. If you find a slot, TAKE IT! You will not regret it!
