I really enjoyed playing a Slick Chick.

Bally Wizard!, Williams Dealers Choice, Bally Freedom, Gottlieb Spirit of 76, Gottlieb Target Alpha, Williams Grand Prix and a lot of other ones...
Not so familiar with 50's games, they are pretty rare in this part of the world...

Everyone seems to like Spanish eyes once I convince them they're allowed to shake it.

Paradise, Grand Prix, Twin Win, Jack in the Box, Centigrade 37, 2001 and Volley to name a handful.

Captain card, Old Chicago, Royal Guard.

Surprised I haven't seen 4MBC mentioned. Seems to be the DMD players' EM of choice.

Regarding YOUR personal taste, that will emerge, after playing many, and also evolve and change over time. Keep doing what you're doing, putting time on these old gems. You might find a feature you really like (zipper flippers, roto targets, back box animation, or spinners), or a designer (sounds like you fancy Ted Zale, and Wayne Neyens designed all those Woodies you mention) or even an artist you fancy. And if you look around long enough, you might find a confluence of all these things. Enjoy the exploration and discovery!

Royal Flush, El Dorado, Quick Draw, just to name a few.

Jacks Open and Atlantis are fun games with a more modern style ruleset.

Paragon & Joker Poker

Paragon had so much going on. It was one of the first game I ever played. I didn't know they could be that wide and have double flippers. Seemed like so many things to hit.

Joker Poker as well because of the uniqueness per ball. Such a great game. Though this didn't attract me to pinball the way Paragon did.

I love everything by Ted Zale. Vfw had the whole row by him by the front door. He was way ahead of his time. Zipper flippers, multi ball, skill shots, ball locks, kick backs, captive balls. He through every bit of technology available at the time at a game. I love his last 4 efforts before retiring.
Joust, 4 million bc, Fireball, and Nip It

I've had guests over for the weekend, and they're hooked on Grand Prix.

The worst kept secret is Bally EMs are hot, I would go so far to say they have displaced Gottlieb in desirability, especially for younger people. A lot less of them around too, most have had the snot played out of them.
Across the board Space Themes and Cowboy Themes would do best, JMO.

Any EM that has been fully restored.

So many good ones. A few not mentioned that fly under the radar. 4 Square, Drop a Card wedge heads. Really love the play and bell sounds of mid 60’s Mayfair. And mid 70’s Hokus Pokus and Super Flite getting a lot of my playing time.

I’m so sorry to be “that guy,” and while I love both those games as well, they aren’t EMs. They’re early solid state titles.

There are lots of non pinball people that when they are at my house, they play Grand Prix non stop.

I’m so sorry to be “that guy,” but Joker Poker has an EM version

What are most popular Bally EMs you recommend?

True. I’ve actually never seen one in person, production was under 1K I think.

Those Gottlieb System 1/EM crossovers are all pretty fun in EM form. People love my Cleopatra. Same rules as the SS version, but with all of the spirit an EM offers. Super snappy too, since all the coils are DC. Good risk reward strategy, and a nice color matching ruleset anyone can pickup on.

Sky Jump, King of Diamonds, Royal Guard, Atlantis are all single player wedgeheads.
2 Players I like Quick Draw, Lawman

Agree with the statement below E M version is more fun. I've been lucky enough to restore three of them.

Hi stashyboy +
@MisterMoberg (?), mbaumle , You and me (and ???) say "EM version of the early Gottlieb SS-Pins - EMs are more fun". Actually me - I never have played an EM-Version - I do have (SS) Sinbad, Solar Ride and Joker Poker. I would like to have the EM-Version - I once started this https://pinside.com/pinball/forum/topic/add-ons-in-the-logic-of-pascal-janin-boards - hmm, not much feedback ...

Pwaka1986 : Whoever likes (many) Drop-Down-Targets likes Gottlieb pins. My favorite is Far Out https://www.ipdb.org/machine.cgi?id=823 - also very good are Big Indian https://www.ipdb.org/machine.cgi?id=257 and Surf Champ https://www.ipdb.org/machine.cgi?id=2459 (and more). I happen to like also Spinning Targets and Vary-Targets so I like to play Orbit https://www.ipdb.org/machine.cgi?id=1724 .
In the early days there were the two-inch-flipperbat pins --- Shangri La https://www.ipdb.org/machine.cgi?id=2110 - Pit Stop https://www.ipdb.org/machine.cgi?id=1806 --- I actually have played in the early 1970ies the Ice Revue https://www.ipdb.org/machine.cgi?id=1262 (with the slot in the lower right corner in the playfield to count played balls, now and then, for fun play an 2 balls or 3 balls "multiball" https://www.ipdb.org/showpic.pl?id=1262&picno=1202 )

Zipper Flippers are fun - mostly Bally-Pins. If You dont expect "having a regular Bonus-Ladder" then Royal Flush http://www.pinrepair.com/ is a very good pin. A classic Williams is Space Mission https://www.ipdb.org/machine.cgi?id=2253 --- how about "Roto Targets" - Liberty Belle https://www.ipdb.org/machine.cgi?id=1438 .

Here http://www.pinrepair.com/ to Gottlieb Pinball Evolution and Williams Game Evolution - stuff to look at, read.

Play as many EMs as possible - some are soso - some You will really like. Greetings Rolf

I learned how to play on Aladdin's Castle. Any EM with a spinner is a hoot. The clicking noise of the score wheel and the chimes trying to keep up is an extremely satisfying sound.

My guests have always gravitated towards Space Odyssey. They love the swinging target and get really into it, even if it's mostly just them trying to catch the ball and feed it into the kickers.

Old Chicago has been very popular at our league
