I've been playing with Mr Greer for over two years, he is a great Gamemaster, very accommodating to character backstory and including it in the campaigns he runs. Though not a new player myself watching and experiencing new players learn from him from my opinion is very well done, everyone that learns to play from him learns pretty quickly so new comers you'll be in good hands. His world building is immaculate and very interesting, he's very good at twists and homebrew overall you'll be having a bombastic time playing in his games.
