I think you meant to say Grahf was awesome and the best part of that whole sequence.
Plus his theme music played during the unwinnable part of Stone's boss fight.

Congrats on beating Id. He is probably the hardest on-foot boss. Him or one other fight way down the line.

If you didn't take Elly I think you missed out on some very important stuff when you found the nano-girl. I don't know why they made Citan Party Leader for that dungeon when Elly is far more important.

Also have fun with by far one of the worst dungeons in the history of anything and that includes real dungeons where people were tortured to death. Babel Tower is far more terrible than those.

Also, how about some Xenogears Bingo?
