Life is Strange - At least the original, the sequels are not quite as unique. It's an interactive story (though still in 3D) where you can rewind time to redo conversations, effectively making "save scumming" a core mechanic. The designers use the fact that you deliberate on your own actions quite well. The story is also pretty unique, but unfortunately there isn't a good way to explain why without spoiling any of it.
Inscryption - On the surface, this seems like your run of the mill card game. But once you get familiar with the mechanics, some other genres start blending with it.
Edit: Should also add:
A Normal Lost Phone - The premise is that you find a phone that someone has lost, and you can use it to slowly uncover the story of the person who lost it and why.
I recently set up LineageOS on my rpi4 for this. With that setup, I think you'd be able to use the Android version of Moonlight. I haven't used Moonlight before though, so not sure how good of an experience that is on Android. Since the official images didn't support Android TV, I ended up using this version. Performance is a little slow in the menus (and very slow in the Twitch app, but that's also true on the fire stick). I'll probably give rpi5 a shot at some point in the near future to see if that offers better performance.
Bluetooth game controller works quite well (a little too well, the box notifies me when controllers are trying to sync), and works with apps like RetroArch and Jellyfin. I think it's supposed to support AirPlay or whatever the Android equivalent is too, but I haven't tried that. I also had to install gapps to sign into YouTube, but most other streaming apps I tried worked without it. Some of them require specific Android TV devices though, so a 3rd party app store or side loading may be needed for some of them.
I originally wanted to use Plasma Bigscreen with Waydroid, but I ran into the same problem of not being able to find an Android TV image. I did try building it myself, but that was taking too long so I eventually gave up.
