What was the most heartbreaking game tu ever played?

'Time Hollow' in my nintendo DS, because although it ended happily, the actual plot was messed up and too many people died and came back to life .-.

Loz wind waker

Walking dead CLEMENTINE NOOO WHY DID LEE DIE ;-;

The ending of mass effect 3 broke my heart.

Ninstarhal took my first choice... so i'm going with my second...
Halo Reach...
