I understand what I need to do...my question is... can I go back and get the treasures/destruction spheres I missed? I missed the one in Djose Temple because I completely forgot about it...and I need to go back to get it. But, everytime I do, the guards push me away and tell me traitors aren't allowed. Can I get past them somehow and get what I need?

Well, how far into the game are you? I think later on in the game you eventually are allowed back into the temples. (Almost completely positive anyway)

I just beat Yunalesca a bit ago and I'm getting the hidden aeons and weapons, but I still have yet to battle Sin.

Hmm...I think you have to defeat Sin first before they allow ya back into the temples. Once again, I'm almost positive. It's been awhile since I played FFX, so my memory of the game is kinda rusty.

Dangit.... I suck at life. oh well, thanks anyway. :-)

Lol. You don't have to defeat Sin to get back into the temples, you just have to visit the Highbridge in Bevelle and have that large cut-scene with Maester Mika. After that, the temples allow you back in.

When I played the game in my first run, I actually purposely skipped the Destruction sphere puzzles for all of the temples because there are cutscenes when you go visit the Fayth again. You actually get some pretty useful spheres like the White Magic Sphere. Keep in mind that all temples (except the Baaj Temple. Anima is enough of a gift in my opinion ;D) have gifts/cutscenes for you when you visit the Fayth a second time.

it depends !!

some versions have the Dark aeons that won't let you in even if Mika's had !!

scyer is right u jus have to visit the highbridge and jus revisit all the temples doing the destruction sphere puzzles. the one for bevelle is closed though but u needed to get it in order to get out of there so its a given

Dangit.... I suck at life. oh well, thanks anyway. :-)

awwww.. lol

FFX kinda annoys me a little... still good though.

to get anima just make sure you get all the destruction spheres and collect the secret items in every temple throughtout the game then go to baaj temple, simple. if you miss any spheres you can go back to them later on in the game
