Oh, c'mon. You didn't figure out that Seymour was, of course, going to become a bad guy, along with his cronies? FFX's overall plot and the game itself are linear. You know right away that you're going to fight Sin at the end. You know right away that Khimari and Tidus will become friends. You know right away that Auron has some relation with Sin. You know right away that Yuna and Tidus will eventually get together. Yeah, it does have its miniscule twists and turns, but they aren't large enough to warrent a full-scale plot-twisted story. It is nowhere near like FFVI, VII, or VIII where you go, "WHAT?! SERIOUSLY?!" The lack of a world map made the game a puzzle-board where you have to go from Start to End. There's no arguing with that fact. Even the roads were straight paths with very small pathways branching from the main road.
