This question cannot be answered with certainty because much of it relies on the country in which the game is being played. Fangames are typically seen as being legal so long as they don’t violate anyone’s copyright. There are a few exceptions to this rule, though. For example, if a Fangame incorporates copyrighted content from another game or media source, then it may be considered an infringement. Certain Fangames may also be unlawful in some places since they are seen as gambling products.
