I've only seen it in the s thread once, and just up voting it didn't seemed enough. I've played the majority of games people are mentioning here, some of them are quite sad and hit you like a punch in the stomach. Another one I also didn't cried but felt very strongly about it and I don't think I've seen it mentioned here was Life is Strange, there's one particular scene that got me very hard.
All of this is to say, I don't usually cry on movies, books or games, it's not a "boys don't cry" kind of thing, I don't have a problem with crying or with getting in touch with my feelings, I just don't cry very often or for any reason. However, I don't know if it was the story on its own or the blinking mechanic but Before your eyes had me crying, and wasn't just a couple tears either, I only held myself together because I couldn't leave the game until it finished. That game was an experience, I recommend going in blind and using the camera.
