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’s still nothing like XCOM:Long War, but fortunately the aliens are always waiting to take another swipe. Maybe this time I won’t rush mec.
Also I really like Wildermyth. It scratches the XCOM itch but your soldiers retire and have kids and can leave you for more reasons that just because you fucked up. And they can turn into were bears
