Digimon World 3

Digimon World 3 (デジモンワールド3, Dejimon Wārudo 3?), also known as Digimon World 2003 in Europe and Australia, is a role-playing video game created by Bandai for the PlayStation. The series is the third installment in the Digimon World series and it was first released on June 5, 2002 in the US and then on July 4, 2002 in Japan and November 15, 2002 in Europe. The game tells the story of Junior, who begins playing an MMORPG called "Digimon Online" with his friends, but when terrorists attack, Junior and the other players are trapped within the game and must find a way out using his Digimon partners.

For its similarities in the concept and in the storyline, Digimon World 3 can be considered as a prototype of the later .hack game series (also published by Bandai).
