For me it’s first person puzzle games. I can think of maybe a dozen off the top of my head that came out in the last decade. I especially enjoy when they’re open world. The ability to just quit a puzzle that’s stumped you and go try something else for a little bit is incredibly refreshing.
Rhythm Games like Guitar Hero, Band Hero and DJ Hero. Those were fun.
There are still plenty of them: DJMAX, Muse Dash, Spin Rhythm, Hatsune Miku Project Diva, Beatmania. Also there are tons of them on mobile.
