3D&T, formerly known as "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. History Origin 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. 4D&T 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. 3D&T Alpha In May 2008, Cassaro was told by Guilherme Dei Svaldi, editor-in-chief at Jambô Editora, that he found 3D&T to remain very popular, despite being out of print for years. This surprised Cassaro, and gave him the idea of bringing 3D&T back; it was released again in
