A lot of the activities only reward you with items you can use to cook or boost your stats temporarily. However, most of these are largely unrewarding. This includes racing, Dragon Ball-collecting, fishing, hunting, fighting dinosaurs, and even random battles. There are various tasks that you can perform. That means you can go off on side quests to break the boredom of having to follow a linear storyline. However, the game-though not fully explorable-has many open areas that you can wander around in. Those are the restrictions of following a preordained story.
