Maybe this doesn't count, but I remember thinking that Skyward Sword was an amazing game when I was a kid (first real Zelda game and all).
But revisiting it now that I'm older lets me see the flaws that the game has much more clearly. While I still think that it's a good Zelda game (and a good game in general), I don't think of it as highly as I used to.
I remember when I downloaded vice city on my PS3, it had been years since I was able to play it, and holy moly are those some old controls
while I've gotten well used to them now, I always remember that whiplash I felt when I actually felt how it played for the first time in a long while, you get so used to what's new that going back to something can take some readjusting, no matter how long you've played it for in the past
another example is when I had gotten into the 3ds xl, I went back to play my gba and really felt how small it was in comparison
