I believe the future of online gaming hinges primarily on the assurance of a secure platform. Introducing standardized tests or ratings for games based on their coding integrity is imperative. It would be beneficial to have a second-party assessment affirming the soundness of the code, thereby assigning suitable grades.
This would provide long-term players with peace of mind, knowing that the games they invest years into are built on a solid foundation. (GPT version of my edit) (integrity - is a large word here and totally effective)
