I was wondering, in FFX-2, if you get 100% game complete at the end. Then a fayth will appear from Bevelle and ask you if you want to see "him" again, meaning Tidus. What I don't get is how could a fayth appear if they all died in Final Fantasy X after Yu Yevon was killed.

One more question, what does Luck do ? I have been playing FF for ages and never found out what it does but it's supposed to be a good stat.
