Your saddest moment on a videogame

There were many sad moments in games. Mostly angry moments, because nothing went well in the end. But still, although I've seen many sad ending, I think this category can be easily won by Valiant Hearts: The Great War / Soldats Inconnus : Mémoires de la Grande Guerre.
SPOILERS
I'll let you see the ending and some youtubers reactions to understand how many tears were shed for this game. ;)

Witcher 3 - Baron story :/

• Valiant Hearts: The Great War
• To the moon
• Life is Strange
• Papo & Yo

My saddest moments where when I had to go back to normal life after being immersed in a game for countless hours. The 2 games coming to mind where I had the most this feeling:
-The longest Journey: I was so attached to April after spending a long time playing this game, young adult setting where people expect a lot from you and you just want to live your normal life, that I was limit depressed when I finally reached the end.
-Red Dead Redemption: you spent 50+ hours on your horse wandering in the plains, hunting animals, reviving spaghetti Western best moments and then at a certain moment the civilisation kicks-in (when you reach Blackwater) with those damn cars and brick houses...

When my brother erased my Pokemon Yellow savefile with 150 pokemons, missing only Dragonite and I had Dragonair just 2-3 levels shy of evolving.

My saddest moment was not too long ago, when I finished the first chapter of Life is Strange and realized I need to buy the next chapters before I can continue playing. Oh, humanity!

This War of Mine.
The whole fucking game

So many people have mentioned the big spoiler in FFVII, but honestly the ending of Crisis Core hit me way harder than the original did. I think it had something to do with the brilliant mix of knowing it was coming from the start, feeling like the character had so much more story to tell, and the long, drawn out nature of the final fight (assuming you actually tried rather than just letting it happen). But man, the memory reels disappearing one by one? Fuuuuuck that was sad. :(

well it's probably been said a dozen times but: to the moon.
It's the only game where I felt like shit at the end.
A bird's story as well, total disappointment :D

Final Fantasy VII - Aeris death

when mona sax dies in max payne 2 :(

The Valiant Hearts Ending was a sad moment

Spoiler
Check this video to see youtubers reaction about this ending

They've all been mentioned, but TWD, Valiant Hearts and Baron from Witcher 3 come in mind.
Also The Cat Lady.

Winning a game on Hawken while my pc was turning on fire

Super Mario Land on Gameboy. When the credits Start showing up with the music I feel like being thrown back to the early 90s when I played through my First time :')

Also I remember I was really upset when I finished Monkey Island as I regretted thinking this was indeed the end of that game. Was highly delighted when Monkey Island 2 came up though ^^ But the Ending of Part 2 was hilarious and sad at the same Moment! I always feel sad when a funny game ends that brought me so many laughs.

When the cyborg girl dies in cavestory

Another World ending. Very good old game btw.

Since i'm father to a 4 y/o boy and can't even bring myself to buy "That Dragon Cancer" that's how depressing the game is.

I don't know if anyone remembers this game but Radiata Stories was sad for me when I had first played it. Well the ending was sad at least, I only played the elves ending though so idk about the human story.
