The ending of Red Dead RRedemption.. In spite of me not really being that attached to the characters, it really hit me hard. And I don't cry that easily. The only reason for me crying over the past 3-4 years were when my girlfriend broke up with me (cried once, got back together with her, then broke it off again without crying), and then sometimes when I listen to certain music or watch a movie. I don't often weep for real life things.
It is kind of weird only crying because of music and movies and a single game..
