It's a good, interesting game. But not a top 10 in my book.
I've played it on route and in the home environment. On route, where almost all of the 12 machines were being played - I was the only one to play GB. Both times I was at this locale. One guy and his buddy commented while looking over the machine "Game looks cool but not worth the money. Ball times too short, too hard." They watched me play, a short ball time game. Then commented "tough game" and walked away.
At friends houses, played GB and one out of every 5 games I can get a decent game going and start to explore. Interesting shots that I'd like to explore more. But, I can't recall a game where I've had more airballs, straight down the middle drains, and outlane "jump overs". This game needs tweaking in my opinion to give the player more of a chance. This isn't IM or Tron hard, this borders on stupid hard. Fix the outlines at least with a kit.
Fun, interesting and a good game. But not a top 10 yet in my book. Honeymoon is not the best time to determine a game being a "top game".
