Are there any games where your opinion on it has changed substantially over time?

For instance, the first time I tried Metroid Prime, as a dumb kid with zero experience of the genre or series, I was taken aback at how slow and puzzle-oriented it was as I kinda expected something more like say Halo. At such, I wasn't impressed.

After going back and replaying it years later with the right expectations, however, I now consider it one of the best games ever made.

How about you?

Super Mario Galaxy 1 & 2. As somebody who played Mario Odyssey as his first Mario, I despised how the games limited freedom and movement expression. Mario 64 was another one that didn't click for a while for the same reason (plus it felt nowhere near as silky smooth to control Mario as in Odyssey).

Funny how now all three of these games sit up there among my all-time favorites.
