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.
I have hundreds of games in my steam library with no in game purchases or lootboxes which I have enjoyed for between 50 and 2000 hours each. If you really have that much trouble finding games you can enjoy playing, then you need to change your habits.
