I have a Game Show, as one of my two pins. It was my first game I bought, and while I would have loved to have gotten something a little more "popular," I got a good deal on it. Plus, I was happy to have a pin at all.
It's not a bad game. Easy to understand rules, fun sounds/music/shots, with ok difficulty.
Solid 7/10.
I don't have a lot of confidence that it's going to hold up interest-wise for years to come, but if I have a few more pins in my collection it will be a good family machine for guests and kids to play.
