Just about the same here except for me it’s just that I don’t have the time to play every game I want to. The Steam Deck has helped me to play more and fit a little bit of gaming in here and there. I did get Final Fantasy XVI right at launch and set aside a lot of time to play through it.

But to answer the OP, probably Dark Souls. I played it a little at a friend’s house years ago when it first came out but never actually bothered to buy it until the end of 2021 when it was on sale through Steam. Immediately played through it, fell in love, then played through the second one. I haven’t played the third yet, but it is on my list.
