I own a GOT Premium and recently put in a few hours on a GB Pro at the local pool hall. I like GB but I think GOT has way more staying power with the different houses and modes, etc. I kind of hate the Slimer toy on GB. It seems the ball hits slimer and just dies and then of course the ball goes SDTM!!! Of course I would love to one day own a GB but I have no buyers remorse and glad I spent my money now on GOT!!
