Sandbox RPGs allow the player a huge amount of freedom and usually contain a somewhat realistic free-roaming (meaning the player is not confined to a single path restricted by rocks or fences etc.) world. Sandbox RPGs are almost always western rather than Japanese and contain similarities to other sandbox games such as the Grand Theft Auto series with a large number of interactable NPCs, large amount of content and typically some of the largest worlds to explore and longest playtimes of all RPGs due to an impressive amount of secondary content not critical to the game's main storyline. Sandbox RPGs often attempt to emulate an entire region of their setting. Good examples of this small subgenre are Morrowind, Oblivion and Fallout 3 by Bethesda and the Gothic series by Piranha Bytes.
