I bought a flintstones a few months ago and really enjoy it. A friend in NC says his flinstones would be the very last game he sold if he had to sell all of his games. It really is fun. I've not played the other 2 games so I can't make a choice but I can say that flintstones is a great $3000 +/- game.
It's funny how fickle and wishy washy the pinball community can be. 15 years ago you couldn't give a baywatch away. Everyone hated it. Now it's sought after?! LOL crazy. That's why i don't put ANY stock into what other pinballers say about a specific game.
Case in point, everyone HATE HATES HATES the WWE LE for some reason. I have one now and love it. Many agreed upon "dogs" are actually great games if you just get over what the masses say and give them a chance. .
