Digimon World Data Squad ((BETTER))
The plotline is fairly self-explanatory. You're Marcus Damon, a Digimon tamer and a member of the DATS, a squad of enforcers that polices the real world for invasions from the Digital World, the place from which all Digimon originate. As the game begins, a new invasion has begun, and you're sent on a quest to discover why this has happened and put an end to it by turning all of the renegade Digimon back into Digi-Eggs. As you progress, you'll meet up with your friends and battle alongside them against your foes. That's basically the gist of the story; fortunately, it leaves a lot of room for the writers, as all manner of things can and does happen within that context. There are even a few plot twists that occur as you progress, making the plot undoubtedly one of the most refined elements of this game.
