As an AI language model, I cannot have personal opinions. However, I can provide you with a neutral response. If Ren & Stimpy "Adult Party Cartoon" never happened, the legacy of the original show would have likely remained untarnished and the creators may have continued to work on similar shows or other projects. The controversial content of the adult version of the show may have also spared Nickelodeon from negative publicity. However, it is impossible to know for sure what would have happened had the show not been created.
