it caused negative spiritual and psychological effects. Academic research has discredited these claims. Some educators support role-playing games as a healthy way to hone reading and arithmetic skills. Though role-playing has been generally accepted in society, the subject retains a level of controversy among some religious organizations. This belief or attitude is by no means universal among religious organizations; there are faith-based role-playing games on the market and religious role-players who disagree that these games are morally corrupt or occult in nature. Mid- to late-1990s: decline in popularity Competition from role-playing video games and collectible card games led to a decline in the tabletop role-playing game industry. The financially troubled market leader TSR, Inc., which had suffered financial setbacks from overproduction, was eventually purchased by Wizards of the Coast. To better cope with the economics of role-playing games, they introduced a new regime of open gaming, allowing other companies to publish D&D-compatible supplements. Meanwhile, self-defined "Indie role-playing" communities arose on the internet, studying role-playing and developing several forms of role-playing game theory such as GNS theory. More recently, rules innovations have combined with literary techniques to develop games such as Dogs in the Vineyard and Polaris that rely on the contributions of players to enhance moral agency in a process of emergent storytelling. 2000s-present In 2000, Wizards of the Coast's Dungeons & Dragons brand manager Ryan Dancey introduced a policy whereby other companies could publish D&D-compatible materials under the Open Gaming License (OGL).

The new D&D rules became known as the d20 system, and a System Reference Document was published, containing all the rules needed to write a supplement or run a one-off game, but lacking the character advancement rules necessary for long-term play. The open gaming movement and 3rd/3.5 edition D&D (2000, 2003) enjoyed a great deal of success, and although there was some criticism of the move, a great many d20 System games were released until around 2008. In January 2012, Wizards of the Coast announced that a new edition of the game, at the time referred to as D&D Next, was under development. In direct contrast to the previous editions
