The game isn't that interesting from a layout/shots perspective, but it has some of the best code ever, in my opinion. If you're a decent player who is willing to put in the time to learn a deep ruleset (whose basic components are pretty straightforward, but very deep and nuanced in how you choose to play through it), this game will last a long, long time in your collection.
But, if you just want to bat the ball around, Game of Thrones will be really unsatisfying.
Also, I vote for the pro as well. The upper playfield is not compelling, not well integrated, and mostly just blocks your view.
