Which game on Steam made you cry?

To The Moon.

Anyone who doesn't say this either hasn't played the game or has no soul.

Definitely The Walking Dead

The Walking Dead is by far the most emotional game I've ever played, and it made me feel things for people in a game I never imagined possible. GOTY 2012 by FAR.

I remember when I bought MW2 (yeah was a stupid idiot) and the same night steam was like ultra overloaded, and steam wouldn't update on my pc, I started ragin to hard, almost cried, just like this video - angry German plays FarmVille.
Story plot: don't buy cod, EVER!

I though Dear Esther was pretty sad. It didn't make me cry though, just sad.

The Walking Dead and Batman Arkham City was pretty sad

ep2, portal 1,2 (sad endings)

None, but Episode 2 was the saddest game I've played for the ending.

Half life 3.
