There are a number of NES and SNES games that I played extensively as a child, but hadn't touched in years. When I went back and replayed them, I was generally nowhere near as good as I used to be. Tricks I used to pull off effortlessly were now beyond my skill level. I also lacked the motivation to replay the same level over and over or to explore as fully as I used to. But, going to some of the tougher levels, I could handle them better with less practice than I needed when I was younger. So some aspects of my game skills are better as an adult than they were in my childhood and teenage years, even out of practice.
