3DeT: Бразильская ролевая игра и её эволюция

Brazilian tabletop role playing game

3DeT, formerly known as 3D&T or Defensores de Tóquio, is a Brazilian tabletop role playing game, created by Marcelo Cassaro. It is designed to be a very simple, beginner friendly game system.

The name of the game is a pun on the famous Dungeons & Dragons or "D&D"; the original version of the game – Defensores de Tóquio ("Defenders of Tokyo") – was a satire of tokusatsu, fighting games, and anime series. It was created by Marcelo Cassaro and published by Trama Editorial, later known as Editora Talismã. It spawned "AD&T" as implied by the name, an "advanced" edition (and a pun on AD&D). Finally, "3D&T" means "Defenders of Tokyo 3rd edition". The major change on the 3rd edition was that it was turned into a generic game, dropping its satire roots. It was a huge success, becoming as popular as Dungeons & Dragons and Vampire: The Masquerade among Brazilian roleplayers. An even simpler version, like GURPS Lite called "3D&T Fastplay", was made freely available online. A revision, "3D&T Manual Revisado, Ampliado e Turbinado", was released in 2003. Dissatisfied with the poor management at Talismã – also publishers of RPG magazine Dragão Brasil, of which he was editor in chief – Marcelo Cassaro left to start a new RPG magazine, RPG Master for Mythos Editora, a magazine entirely dedicated to 3D&T (although the news releases for other systems) and soon after, Dragon Slayer, fully devoted to the d20 System; meanwhile, Talismã kept publishing 3D&T, despite not having the rights to do so. Ultimately, Dragon Slayer was very successful and remains in print, while Talismã closed their doors.

As a successor to 3D&T, a new system named 4D&T was published in 2006 by Editora JBC (Brazilian publisher of manga). It completely dropped 3D&T's own fast, in this the player uses 4 six sided dice. The book was published under the Open Game License. This edition is itself a change of the d20 System, but with six sided dice. Although it has succeeded on its own, it has been poorly received by 3D&T players, given the original purpose of the system was to be as simple as possible.

In February 2021, a new version of the system was announced, called 3DeT Victory, this version again brings a simpler system. There is currently a beta version called 3DeT de Rodoviária, similar to the old Fastplay versions. To make the publication viable, on August 4, 2023, a crowdfunding was launched on Catarse.

Defenders of Old Tokyo created by Ricardo Cavassane is a retro clone of Defensores de Tóquio, the game was praised by Marcelo Cassaro.
