Lots of games actually. I spend a great deal of time wondering how the hell child me did half this crap. Used to be able to speed-run DuckTales(without taking any damage), SMB2 and 3(no warps for either), and Metroid. Recently DuckTales took me a few tries, I got stuck hard on the final level in SMB2, struggled like hell just to reach world 8 in SMB3, and got completely lost in Metroid and gave up.
On the flip side, I'm better at some games I just could not do well at as a child. Back then I couldn't get past Level 3 of TMNT, and I never got far in Castlevania games. Now I can beat TMNT with ease, and can regularly reach Death in CV and Dracula's castle in CV3.
Reflexes and thought patterns change, I think that influences your play-style.
