There are numerous side quests in FFX, but you can't really get to them until late in the game (after the airship). There's a sport that you assemble a team for, managing free agents and competing in leagues and tournaments. The prizes for winning these are often items that can't be obtained elsewhere.
The game is DEEP. You can just play right through it and ignore all the extras, but what fun is that?
