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.
There a youtube channel and a steam curator called Mortismal Gaming who loves CRPGs. Their shtick is also completing games at 100% before popping a review, and they are churning out new material at an amazing pace. Check it out for some decent coverage on the genre.
As for a maybe hidden gem, Age of Decadence looks pretty good. I have not played it yet, but the genre seems to match, and the premise is solid.
Expedition Rome is well appreciated too, even if it leans more toward tactical battles.
