Here’s my list:
70s: Stars - I love the weird period where games went solid state, but still used chimes and Stars is just a great game. Honorable mention to Joker Poker.
80s: Taxi - This is a nostalgia pick. I played a ton of Taxi growing up. It’s also got a great layout and theme integration for the time period.
90s: Whirlwind: I love some Whirlwind, but honestly for me the 90s doesn’t hold up as well as it does for other folks. Whirlwind is my favorite from the era with Funhouse as an honorable mention.
00s: Simpsons Pinball Party: Great theme integration and great code. The only thing that made me sell this one is that the ball times at standard settings were sooooo long. Like 60 minute games.
10s: Jurassic Park Premium: This is the pinnacle of pinball for me. Great code. Great layout. Great theme integration.
20s: Rick and Morty: This is a close second to Jurassic Park. My game was one of the last off the line and it flows so well and shoots like butter. The theme integration and code are great.
