The NCCRPG is set in a near identical replica of the Naruto Universe as depicted by the anime and manga, following it's geography exactly. One of the key differences however is that the game is significantly more limited on the amout of villages on offer for a person to create a character into, that being the villages Konohagakure (Village Hidden in the Leaves), Kirigakure (Village Hidden in the Mist), Kumogakure (Village Hidden in the Clouds), Sunagakure (Village Hidden in the Sand) and Iwagakure (Village Hidden in the Rock).
The NCCRPG follows the same ranking system as the anime and manga source itself, where people are given a rank dependant upon skill. These ranks are Student, Genin, Chuunin, Special Jounin, Jounin and Kage. Other additional ranks do exist, but they are dependant upon circumstance and the village itself.
Members of the NCCRPG must abide by a set of literary and social rules on the site, as well as certain gameplay rules made to ensure fairness for all users.
