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.
Gitaroo Man is fantastic. We need more games where you can defeat enemies using the power of your rock.
Brutal Legend also, although not the same genre by a long shot.
