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.
