This topic isn't about necessarily what are your favorite movies, games, etc...but rather ones (And they can be among your current favorites) that have a special place in your heart whether it be for nostalgic value, or if they sparked or resparked your interest in something.
For me, I have special places in my heart for....
Movies:
Halloween 4: The Return of Michael Myers, Halloween 5: The Revenge of Michael Myers and Child's Play 2 for being the first slasher films I saw fully and sparked my interest in the slasher genre.
Rat Race: The first PG-13 film I saw in theaters. (I was younger than 13 when it came out obviously) I found it hilarious then, and I still have a special place in my heart for the movie.
Games:
The PS1 Final Fantasy Trilogy (7,8, and 9)-I played first played 7 when I was either 6 or 7, and I was hooked instantly. Even though I was too young to understand the story, I loved the boss battle music in 7 and flying around the world map on the Highwind. The same goes with 8 and 9, with 8 having IMO the best airship theme.
F-Zero for the SNES. My first video game and racing game, it got me hooked on the genre instantly.
