Have you ever played a game and then there was one particular part that you really felt changed you somehow? If yes, what game, and what moment? (Please use the spoiler text, so people can avoid your comment if they want to)

For me it's from Pokemon Mystery Dungeon Explorers of Sky! Almost at the end of the game your companion Grovyle (which was a villain in the game for a long while) sacrifises himself for you. It really was a very emotional scene, even though it might be hard to explain why. The game had been building up for this point for a long time, but I wouldn't have expected that to happend. It's the only point in any game that I have started crying, at least a bit (manly tears FTW).

Pretty much the entire experience of Majora's Mask...

Oh well, couldn't remember those threads. Anyways, when it comes to the mario 64 moment, I'm talking about a specific "something" that changed you as a person more than how your view is on gaming. 

There were many in Persona 4: Golden, especially in the later levels of certain people's social links.

Gaming moments that changed my life:

The end of Braid
Passage
That moment in Kid Icarus Uprising where they have you play as a little girl in a war zone for 1 minute.

ohh its not that i was saying i made a thread about a similar subject, but just pointing out two important moments in gaming for me and didnt want to retype them

and well i dont think any moment in gaming changing my life, thats a big thing 

Tower Knight in Demon's Souls.

Oh, well it's all good then :D 

And yeah, it truly is a big thing, but that moment I experienced in PMDEoS (long abbreviation) really stuck with me, and I think it actually made me appreciate my friends more. 

a.k.a., Manly Tears: The Game
