This is what I remember finding on route around 73 and later. Not necessarily listed based on when they appeared on route.
Champ, Air Aces - loved them both.
Galahad - What can I say? It was there, we played it. Not much of a game. I think it being slower than the other two games at this location made us "learn" on it.
Op Pop Pop - Interestingly weird. It was one of two games at the Roller Rink so we played it.
Sky Rocket, Expressway, Firecracker, 4 Million BC - All got my attention at a dime a play. 4 million probably wins out as best.
Sky Kings - Same layout as Champ, much better artwork. Love them both.
Amigo - love the artwork. Simple game play, attracted me back to it at the time.
Ditto for Flip Flop. Bottom drains are a bit of a tease. Requires fresh rubber and good nudging skills.
Delta Queen - Replaced a Crescendo. Definite improvement. Art is so so. Game play was fun.
Space Time/Time Zone - seemed to be everywhere and we played it. Can't stand the game any longer.
Ro Go - interesting layout using a lot of Space Time or Monte Carlo. Fun to risk the turn around look for 5000/5 Adv and special when its lit. After all, its right there in your face, How can you miss???
Fireball - I have heard it is a good game?
Odds and Evens / Monte Carlo - Both great games and art. Monte wins out for better rule set. Which is odd that the single player is less attractive in that way.
Old Chicago - Absolutely love it.
Bow and Arrow - Great Game!
Wizard and Capt. Fantastic. Yes, we played them a lot. Probably a tad overrated these days. Certainly true for Capt. Fan.
Hocus Pokus, Aladdin's Castle - Both Fun layouts. Great Artwork.
And Later came games like Night Rider and Freedom in EM form. Good offerings but they paled once their SS counterparts began to appear.
As you can see, I had very little exposure to the earlier 60's games where and when I grew up. I'm not sure if it was related to the Los Angeles Pinball law (I did not actually live in the city of LA) or if the locations were just too valuable to let the older games take up space. When I started playing, the oldest games on location around were: Op Pop Pop (69), Galahad (70), Funland (68), Mibs (69), Mini Cycle (70), Crescendo (70), Aquarius (70), 2001 (71), Hayburners II (68), Gridiron (Pitch and Bat - 69), Straight Flush (70), Jive Time (70), Doodle Bug (71) Klondike (71).
