I definitely concurr, it's a grey area.
But again, just for the sake of the discussion, it's not obvious to grasp the legal difference (if there is any) between modifing the database changing, for example, the characteristics of a torpedo, or the top-speed of a sub (also a playable sub) or the range of a sensor (also the ones used by playable units) and changing the characteristics of a playable unit (thus making it an altogether different unit).
