1) Who was the older Kos-Mos? (I know this might be a poiler question so if it is, just don't answer)
2) Could it be that Jr is Fei's older incarnation? I'm saying if Albedo -who is Jr's dark side- can be the key to Abel's place then he might be Fei?
3) Why's Shion semi nude in the intro

?
4) If Xenosaga is after the event where Humans first reached Earth (Or xenogears planet) since they've mentioned Abel, how could it be that with such technology they couldn't reach their planet?
5) Is the anime a direct conversion of the game? I mean with the all the stupidity of episode 7

?
6) Someone said that there's a mission from the game that's just mentioned as a flash back in the anime. Is it the one where the cyborg saves Momo?
7) Is the soundtrack of the anime the same of the game?
8) Is the story writer Masato Kato?
9) Tell me all the referrences from Xenosaga to Xenogears. I was able to find very minor ones, I hope you give me some more, again with out spoiling any thing from Xenosaga 2.
