i cried 4 times, thinking about DMC4!!!

Right here!  There have been acouple of other times though.

 Oh Em Ef Gee

I didn't think anybody else in the world had read where the red fern grows. Pretty sad ending, didn't tear up over it though - English teacher was pretty much bawling though.

But yeah, sad sad ending. Shindlers List is another one that really touches you. 

cmon guys, we're man, we don't cry...this is VGChartz, do you remember? the place where are 10000 single man... and men don't cry... :P joke

I almost cry when Dumbledore died, when Dobbie died...
In a movie, in spanish is called "el zorro y el sabueso", its about a dog and a fox that become friends.... It was too sad when the old lady left the fox in the wood....

Grave of the Fireflies... Oh geez I almost forgot that movie... So sad! TT_TT

Grave of the Fireflies is literally the saddest movie I have ever seen.  Absolutely heartbreaking.

 THat would probably be the Disney movie the Fox and the Hound.

I almost cried at the end of MGS3.

 I almost cried at the end of HL2:Ep2.

Also Folklore kinda makes you sad hearing all the stories of the town folks.
