If you could only buy one game for your playstation 5 which would it be?

To explain the question more, imagine your backlog and game library was wiped and you could only buy one game for the rest of your life, which game would you buy? Wanting to see what banger games yall will throw out and see if I have them in my backlog. Finding it hard to focus on one game and play it through. Want to be able to play a game I have or pick up a game that would possibly hook me.

Ni No Kuni was one of those games that did that and I've finished. Have at it!

Edit: I may end up tallying up the results but so far a bunch of: Elden Ring and Hell Divers 2
