Game noncomplete

Today I was just thinking, is it just me or is it harder to actually complete a game these days? I remember a time long ago when games were easier to finish. I remember how satisfying it was to get every achievement every extra item, every cosmetic or alternate ending. I think the last game I actually finished was Resident Evil 2 on PlayStation.

Why is this? Do they (the Developers) just make it more difficult, more elaborate? I understand that people want to be immersed in the fantasy world, but really, who has the time for this? Only the one percent can claim dedication to honing of their craft and have the ultimate title of completionist. All I know is that I'm not one of them.
