Undertale - Main Theme (Once Upon a Time)
Memories:
-
Once, years ago, a friend asked me if I had played/beaten the game "Megalovania". This song is so iconic that he thought the ENTIRE GAME was called Megalovania.

Sign: "press Z to read signs" Seán: "Well I'm playing on a controler" He said the exact same thing the first time as well.

My mom was told she was very very sick lately and I wanted her to play undertale/deltarune with me as she’s never played games and I wanted her to experience the game closest to my heart. When this song started playing I broke down in tears and spoke my feelings like I never had before but she didn’t notice. She was so captivated and after that made me want to cry more. She beat the game true pacifist and she said it was a nine out of ten. I’m thankful to have this memory, I won’t forget.

so weird to hear someone describe undertale as "nostalgic" and "apart of their childhood" when it feels like it only came out last year

You know you've been in too deep in the Undertale fanbase when you're able to recognize every single Sans AU OC to this day.

I’d like to think someone out there is still stuck on the sans fight 10 years later while actively playing the game

Happy 10th anniversary to the game that, with no exaggeration, completely changed my life. I got into the online space because of this game. I learned that I loved to make art and programs because of this game, so much so that I'm studying both software engineering and animation in college. Most importantly though, I met my best friends because of this game. So many aspects of my life can be linked back to this game, and I am so grateful that I found it back in 2017. Toby Fox, thank you so much for making Undertale, my life wouldn't be the same without it.

I was puzzled when you mentioned that this was a pivotal part of your childhood. Then I realized that Undertale was released 6 YEARS AGO. Time flies

Knowing the undertale fandom back in the day, it really is as if the fans back then matured and are still in the fandom. Warms my heart.

You are suddenly filled with years worth of muscle memory for a battle you've never fought...

"Oh this'll be a fun little romp for Christmas, to just casually-" "Howdy~!" *Stands up and starts clapping like it's the Oscars, tears in my eyes*

Eight years ago me and my childhood best friend and first love both got Undertale for our Nintendo Switches for Christmas and quickly became obsessed. One week ago that same best friend committed suicide…today on the bus listening to this song I started thinking about her, her smile, and all the fun we used to have and how I’ll never get that back and how I’ll never her again. I started crying then, and I’m crying now writing this comment. This game will forever have a very special and sacred place in my heart.

"I'm just another person who played Undertale and had it become a huge part of their childhood" Me, 24: crumbles into dust

I remember hating Undertale as a kid because I was a Steven Universe fan and I thought the parody of Stronger Than You was official and Toby Fox ripped off the show

*Seán talking about how he'll probably fail at the voices* Seán nailing the voice: "Howdy! I'm Flowey! Flowey the flower!" Me on the verge of tears: "It's beautyful!"

Seeing all the original videos get taken down, ten years of history... felt like a turning point

* It can't have been 10 years already... * Everything, everyone I loved can't keep getting further away. * I don't want to keep growing up... * Not without you.

Undertale music is one of the reason that made me start doing music, and for that I will always be grateful
