Dragon World is a board game, think Mario Party but without the fun. Basically, you take turns to move around a little map, you meet somebody and then you fight them, and the team with all the dragonballs wins.
That's nothing more than a complex way of having lots of separate duels, much like an alternative style of tournament. The world itself doesn't even seem to be particularly interactive. It'd be great to be able to fly around and explore a planet, looking for the Dragonballs, but that's not what we've got. Instead, we have Monopoly with DBZ fighters.
