Played both back-to-back at MGC.
GB Pro was a lot of fun to shoot. Modes were easy to understand, and I even got a "Mass Hysteria" multi-ball that reversed the flippers. We'll be buying one.
Hobbit? Boooooooring. It's basically WPT with no upper playfield and MM trolls instead. Code doesn't save an empty playfield.
