Final Fantasy VII

Meh, all of FF7 was dissapointing. Most Overrated game ever.

Baisically in the ending, you save the planet from Sephiroth (this bad guy) and the Earth retaliates by killing off all the humans. I think the Earth feared in the future, maybe thousands of generations from that time there would be another Being who would be a threat to the planet if Humans were allowed to live on.
