I really like Ep2. I mean, the battles are tedious and I didn't like the VA changes, and yet... I still love it.
It also has my favorite song from the whole series, I Am Free, from the last confrontation with
. It's only about 100 seconds, and it's a rare track from the soundtrack that only occurs once and has nothing to do with any of the other themes.
As far as the intent to have six games, wasn't it initially supposed to be a trilogy (three parts to the story, with each part comprising two games), and the only character who would appear in all six games (in some fashion) would be KOS-MOS? Why do I seem to remember reading something about that way back when?
