I want an emotionally moving game.

Alan Wake, such amazing writing.

Heavy Rain and The Walking Dead

I want to be the guy

Final Fantasy 7 Crisis Core (PSP) ;-{

• To the Moon
• Machinarium
• I Have No Mouth, and I Must Scream

A few I could come up with off the top of my head.

Free flash game that brought me to tears here

World of Warcraft can make even your wife cry

Portal 2

Fortix

PC: To the Moon, Psychonauts (at times), Analogue: A Hate Story, The Clockwork Man, Dark Fall series (mostly horror), Loom, The Dig, Sam and Max series (mostly comedy, only really emotional near the end of the series).
Other: Persona series, Ar Tonelico, Kingdom Hearts series, 999, The World End With You, Time Hollow

Enslaved: Odyssey to the West, Nier, Red Dead Redemption and Lost Odyssey are some of the most emotionally moving games I played in this generation.. sadly none of em have been released on PC, so I hope you have an X360 ;) Alan Wake is a nice one too, the story and characters have a lot of depth and you have to read between the lines to get the most out of it.

Of course there are many older games that can still touch your heart.. Final Fantasy 6-10 or Max Payne 1+2 for example.. haven´t played MP3 yet, so I cant say anything about it.

I guess this game is without tears, but if you want ponder about everything and experience something unique, try The Path. I never played so deep and meaningfull game. This game is maybe one of the best games I ever played. But it's not game for everybody. You must understant it :)

The Legacy of Kain series if you want to throw yourself in the abyss of great story and characters.

Bastion and Planescape Torment.

Aquaria

Assassin's Creed.
