I want recomendations for games or visual novels that know how touch one's heartstrings. So I want to know which game/visual novel has moved you the most. Possibly with some description of what it is about and why did it move you.

In my case it was the original Muv Luv Trilogy which really hammers down the concept of how great can a normal, boring life when you lose it all. And how can one grow up as a person while the life kicks you in the balls over and over again.
