If I had to choose between GB, TWD, and GOT pro pins, I'd choose GB. I love the theme, it's tough as nails, and has a "one more game" feel suited for a home environment. I have a Pro with no mods and haven't updated the code since I took it out of the box last year (I'll get around to it...but enjoying the game as it is). I personally have a lot of fun with the pin and isn't leaving my collection anytime soon. The only thing that worries me are the playfield issues that I read about on this site. Knock on wood. Haven't experienced any ghosting issues...but it's something to keep in mind.

TWD and GOT are decent pro pins as well. I like both shows. Just felt TWD was a little too gory to add with a toddler in the house. GOT was fun but didn't have that "must have" feeling after playing a few games...although I would be open to adding one to my line-up in the future.

Good luck with your decision and congrats on your win!
