To adapt the story of a novel into a game and present it in a game, the original author had to give permission. This was because the game was a commercial work that had to abide by the relevant provisions of the copyright law. Without the authorization of the original author, it could not be promoted or sold in any form. The adaptation of a novel's plot required modifications to the original work, including the characters, storyline, background settings, and so on. If the adaptation was not done properly, it might violate the copyright of the original work. Therefore, the adaptation of the story needed to consult the original author and obtain authorization to ensure that the adaptation was legal. If the story of the novel was adapted into the game without the authorization of the original author and sold or promoted in the market, it might face legal risks. In addition, if the content of the game is similar or identical to the original work, the original author may complain or sue.
