OK, thanks.
Related to the topic, it was the first video game I can remember that killed off a major, playable character. It was rather shocking at the time.
Now off topic: Still my favorite game (followed closely by Halo). The gameplay, the plot, the villain, the hero(es), the music were all very well done. (Graphics were amazing for the time, but today are long outdated.)
Aside from the Japanese obsession with "We're all destroying the earth!", I have zero criticisms.
