3D&T

3D&T is a family of brazilian RPG systems, which was published by a former brazilian magazine called "Dragão Brasil" ("Dragon Brazil"). This family was, until 2007, the most played in Brazil, because of its simple rules and easy mechanics, using only 6-sided dice.

It had a few editions. The first one, "Defensores de Tóquio" ("Tokyo Defenders", in brazilian portuguese, and also known as "D&T") is a humoristic RPG system that parodize japanese heroes' series ("Tokusatsu") like Ultraman, Power Rangers, Jaspion, Changeman and so on.

The second edition was called "Advanced Defensores de Tóquio" (AD&T). This edition improved the rules but used the same japanese Tokusatsu setting.

In 1998, the third edition, 3D&T, was launched and kept the rules but removed the setting becoming a generic RPG system. A few years after its launch, the edition got reviewed, its rules' modified and it became "3D&T Turbinado" ("Turbo 3D&T").

In 2006, a new edition using the Open Game License was launched, called 4D&T. It didn't was very well accepted by the players because it became more complex and had some design flaws.

In 2008, 3D&T was reviewed again and received the name "3D&T Alpha", becoming an open licensed game as well. This edition is published in paper and via web, which is freely available here.
