Honestly if you don't expect the AI to
fix
the bugs, just find them, this probably isn't a bad idea? I think it would probably work quite well at just running down a big list of trying all sorts of actions/interactions in every place/situation possible and creating a list of where results differ from what you told it to expect
some parts of game QA can get extremely repetitive
THIS IS WHAT I HATE A BOUT EVREY WEBSITE!! THERES SO MUCH PEOPLE READING AND POSTING STUIPED STUFF
