The same for me. I still sometimes find games that I can really get into, but it's much harder than it was 10-20 years ago. I think part of that is because I've played so many games that many new games just feel like the same old again and again. The other reason is, of course, that the general inability to concentrate hard on stuff makes it so much more difficult to immerse myself into the game world.
Some exceptions in the past few years have been Zelda: breath of the wild and GTA V (yes, I know both of them are a bit older, but I only played them relatively recently).
Same here. There is one game though that for some reason I've replayed over and over through the years.
I played the original way back of course. Probably once. Settlers 2.
I had to look it up but apparently the "Settlers 2: 10th anniversary edition" came out in 2006. I don't even remember the original graphics and I'm so used to the 10th anniversary edition look. But once every year or two I delete my profile and play the campaign again over a week or two. It's the only game I've come back to again and again so often. Even with kids in the mix.
