well, first of all: it's kinda obvious that Tidus lives (or else it would hav been a pointless game...) and it's definetly not Tidus speaking in many of the sphere's so why does Yuna continue to believe its him ? i have not played the game through, but its looks to me that Tidus is held in bevelle(play ffx and youll find out why thats so obvious...) in the first sphere which leaves 2 choises: New Yevons got him or he has locked him self in:rolleyes2 . the weapon he referrs to is clearly Vegnagun so why dont yuna and company just "ask politly": about were it is where there must some more clues to where he is. and dont come to me with that "yuna dont like violence" stuff (seriously... SHE'S WEARING GUNS!!!). i'm not saying its a bad game, cause it's not but it's waaaay to obvious...
