Quality: TH
Artwork: tie
Theme: TH, but GB comes very close
Sound: Close, but I vote TH
Rules: TH for depth
Fun factor: tie
Lighting: TH
Game play: TH
Scoring: TH, typical of stern games, scoring is not well balanced on GB.
Intangible: TH because it's the most immersive game I've ever played.
Overall, I'd rather and do own a hobbit. GB feels like it should be a 5k game, the hobbit feels every bit worth the $+/- 8k or so it goes for. Throw a big LCD in GB and this could go the other way.
