Tiny and Big: Grandpa's Leftovers was the first game I played with scenery that was generally fully destructible and you had to cut stuff with your laser gun to make paths to progress forward. The game... was fine. It was a perfectly OK game. But the concept was neat and I haven't seen many other games aside from maybe Noita go to that level of destructible/interactive scenery that makes up a primary part of the overall gameplay. Plenty of games involve breaking shit, but in my experience relatively few ask you to break shit in a pretty specific way so a column topples in a certain direction to allow you to platform up it.
Return of the Obra Dinn also has a really cool mechanic in that the game is primarily played by watching the last minute or so of somebodies life in order to identify the corpse. You walk around a whole boat doing this and piecing together who is who. I've seen flashback style time mechanics in a lot of games but I've never been asked to use it as a detective.
Prey threw a twist into the "alien pops up and kills you" standard space FPS situation by making the aliens able to pretend to be mundane items in a room to get the jump on you. If you leave and come back sometimes they would even trade places. It was kind of underutilized though - I expected to be questioning every coffee mug or slapping every stapler, but really it was just like a now and then thing and the majority of significant danger was the regular ass walky-aroundy aliens.
