if you can go back in the other temples, you should be able to go back into Besaid also. it did me the same way and all i did was go around, fight a while, clean up, etc. and it let me in. good luck. i don't know what else to tell you.
aight, gameman, i'm getting tired of your [censored]. congrats, you beat the game and got all the aeons. most of us did. the ones that didn't come to us for help. thats why this is a GAMING FORUM. not for the people who beat it to get together and brag and laugh at the ones who didn't. we are here to help them. yeah, you can help people out a lil bit, congrats, most of us can. are you so proud? ain't no need in all the bragging and bullshit. every time you post, its all about how beat every game and did this and did that, and all that. guess what? (sorry amy and gerb) NOBODY GIVES A ****. carry that [censored] somewhere else man, nobody wants it here. and whether they post back or not, i'll go ahead and tell you, a lot of people on here feel the exact same way.
