A lot of people like JM I haven’t played it enough.

Flintstones could be a B title on a good day.

Of all the pins I've sold I miss BM66 and WOF the most.

WOF has the most unique strategy of any pin I've played. Even with the incompleted code.

If you like Maverick, consider River Boat Gamble. Such a good and unique game.
From your list, monopoly and wheel are the best bang for sure. Flintstones is great but not for the price they demand these days.

Of your choices listed, I would select Baywatch as best of the group. It's a lot of fun to play. ColorDMD offers a terrific upgrade to the already nice oversize dot matrix display. Much like some who don't like Alec Baldwin's face on the Shadow translite, I wasn't fond of David Hasselhoff on Baywatch, but didn't like the available alternates with photoshopped images of Pamela Anderson. But I just purchased and installed a new comic art style translite which greatly improved the game's visual appeal to me.

This really is up to personal taste. My buddy has Johnny Mnemonic and loves it. He sold his White Water and his Indiana Jones but kept Johnny (partially because he could get more for those other games).

And my choice may not be the best for you, since I have played Maverick on location several times and each time come away knowing that it is a game I never want to own. And I don't "rotate out" games anyway.

There's a place on the playfield for wizard mode but no wizard mode was ever coded.

There is a "secret" code update that I had in mine, but it was mostly for tournaments.

Johnny Mnemonic is NOT a C title!!
I’m amazed it’s on the list. It’s a fantastic game. It’s definitely the low end of the A tier.
