Cant say ive ever cried for a game but there have been a few to give me an emotional response. It usually takes alot to get it out of me but a few gems i can remember are....
Metal Gear Solid 4 - ive been playing MGS since i was a kid so to see my hero break, suffer and win was quite moving to me.
The last of us - dont really think i need to explain this one....
Journey - such a unique experience that spoke to me on so many levels. Such a great experience.
