Xenosaga III was just fine but
what was up with the break system? *groan*
All in all, I think of the three Xenosaga I was the best, mostly because it had the best battle system to me. I really wish they hadn't taken out the particular way that you upgrade and perform special attacks in Episode I.
... Truly intriguing storyline in all three, though.
KOS-MOS and MOMO for the win, btw.
(... I wonder why, of all people, Miss Shauna hasn't shown up on this thread by now.)
