You don't have to be afraid to play video games anymore just because you're an adult, especially with the amount of greatness coming out of PlayStation over the entire PS4 generation.
You know the Nintendo Switch has a lot of games you can play with your wife together. There's It Takes Two, a co-op platformer about a couple forced to fix their relationship, and that game won game of the year 2021.
You can play Mario Kart 8 Deluxe together, or Super Smash Bros Ultimate. Or get some friends and have a fun time with Mario Party. This month Super Mario Bros Wonder is coming out and that you can play together. Warioware is also a really fun game to play together with many different wacky microgames.
Then there's unforgettable single player experiences like Zelda Breath of the Wild (which won GOTY) or Tears of the Kingdom, or Metroid Prime Remastered, or the upcoming remakes of Super Mario RPG or Paper Mario The Thousand Year Door. Fire Emblem Three Houses also has an amazing story that really stuck with people.
