I have a Flintstones and think it's a great game – especially since i was able to get a "clean" alt cartoon translite and playfield sticker.
There are two reasons i added it into my collection.
First reason- it's full of very unique attributes like bowling and the smart ramps. And the way multiball starts is cool/clever.
The second reason was the most important to me.
It's one of only a few "family friendly" games out there that's under $2500.
We have 2 young boys and I want to make sure they enjoy pinball and are not afraid of the game room.
So many pins out there have gun violence or scary/agressive themes that i think are awesome, but not kid friendly.
Some day when they're a bit older i will rotate the collection to have more agressive games but for now I want to make sure I don't scare my kids away from this hobby I love so much.
