It seems like the kind of idea you might just "step over" as being too simplistic. I wish I had the time and energy to just explore simple ideas like this to see if I could create a compelling game or creation out of them. I think it takes a child's creativity, earnestness and positivity in some respects, and I'm afraid to say I'm a bit down on the world at the moment.

If you only consider AAA studios, then yeah, you're right. But step into the Indie game world and there are a lot of new unique concepts being done.

Balatro, Baba Is You, Superhot, Superliminal, and Slay the Spire come to mind immediately.
