That's not really in the spirit of the question though. The question boils down to "what game made you feel some kinda way that you'd like to replicate?" It's entirely hypothetical. Theres too many amazing games that have been made in the last thirty years to ever finish them all. But that doesn't take away from that moment in a game that was so new and impactful that it became seared into. I've had experiences so deep it literally changed how I felt about death and loss and it would be amazing to feel those feelings again.
