Games that you would classify as must-play experience

Sorry if the title is a bit vague! I'm not really picky when it comes to genre. I'm looking for games that left a lasting impact on your experience as a gamer.

Personally, I would cite: "portal", "machinarium", "Ori and the will of the wisps", "hades", "Stray", "limbo"... as games that changed my perspective on gaming.

What games would you recommend that had a similar impact on you? Thanks in advance!
