Okay, lesse...
For an old game, FFVII has several emotional moments. Of course, everyone's heard of the whole 'Sephy goes stabbity-mc-stab-stab on Aerith', and that is indeed sad. Mainly because she's the kind of character you want to sit on your lap and feed cookies all day; she's lovable. This, however, is besides my point.
Back in Disc 1, a little while after leaving Midgar, you travel to Cosmo Canyon. After a fairly tough dungeon -- the Cave of the Gi -- your party (which consists of Cloud, Red and [insert your choice here]) comes to the back of the cave, where the truth about Red's father is revealed. Having believed him to be a coward who left his village in the face of the Gi tribe, Red is shocked to learn that he did not run; in fact, he gave his life to defend one weak spot into the Canyon, through the cave you just battled through. Hit by an enemy arrow, he continued fighting despite slowly being petrified. Stricken with grief at the revelation, Red leaps up the rocks to stare up at his father; still standing fiercely, hackles raised and teeth bared at an enemy long since defeated. He howls mournfully, and as he does so, tiny droplets of water -- tears -- slip from the stony eyelids of Cosmo Canyon's forgotten protector.
That, coupled with the track used in game, very nearly makes me cry every time I see it.
