What unique mechanics have you seen lately that “made the game”? - eviltoast

I’ve been going out of my way lately to find unique mechanics, UI’s, etc. that fundamentally alter and improve a game, to the extent that their removal would severely hurt the game and make it less effective/impactful/etc. To be clear this is less “unplayable,” so not something silly like “removing the right thumb stick from Halo.”

Instead, I think of how Immortality essentially “gamified” and simplified a movieola (35mm film editing hardware) to be the player’s interface with the game. The process of scrubbing through footage, marking favorite clips, cropping in on items of interest, “match cutting” (sort of), made for an incredibly immersive experience. Honorable mention goes to the music raising and lowering or shifting as I sped through or slowed down on footage - it created such a unique gaming experience.

What are some examples for y’all?
