RDR1, but I want to find a good WW2 flight combat to add as well. My 2DS XL can essentially do anything up to PS1, and now the deck takes me the rest of the way.

The tomb raider survivor trilogy seems to be at or right under $10.

I’m currently lost/immersed in the second chapter of rdr2. I know there’s a story but it’s a game that lets you make your own way in a world that’s huge and alive. Of course the story apparently is incredible, I’ve just paused to become a roaming hunter gambler.

I’d say your answer may be environmental. Modern day nyc or 1897 US frontier or futuristic.
