I feel the same. I concluded that I just cant play games as much as I used to, and that actually there's little point, because those feelings will never be fresh in my mind again since it's not a new experience. My opinion is that playing newer games was often me trying to chase those past feelings (nostalgia) but it'll never be the same. Then I figured the reason for this is because I've changed as a person, and I now take more pleasure out of other things in life that games used to satisfy. So now I chase those new passions instead, and occasionally play the old games of my childhood instead of newer titles, since they are much better at giving me a nostalgia hit.
