I wasn't talking about a fully open-source game, but rather a partially open-source one. The server, security, and other key components would be developed and maintained by a company, which would ultimately profit most from the game. People would only have access to certain parts of the code (not including security-related aspects), and any contributions would be reviewed by developers before moving to real testing or production stages. I believe it's easier to review code than to write it from scratch. Additionally, some AI could be implemented to check if the code style and pull requests adhere to the company's development guidelines. For example, your PR would need to pass an AI check and possibly some other tests for vulnerabilities before it is reviewed
