My city is 6 km across (3,7 miles)

For something different you can try The Room games. Definitely not life changing but atypical.

What genre? Those are some peculiar games. I guess you might like Strange Horticulture.

Otherwise for a mix bag: TPS/Adventure: Horizon Zero Dawn Arcade racing: Hot Wheels Unleashed TPG: Baldur’s Gate 3 FPS: Halo Master Chief Collection

Never have, I travel a lot and always carry my Deck, not a scratch on it.

Do these other handhelds sell enough to justify all these different devices?
