There isn't really a way to make it into a legit journalistic field because it's pretty much just an industry about personal opinions. Even movie reviews, which are considered respectable, are hard to call journalism. Roger Ebert was a cool guy and all, but he wasn't a hard-hitting journalist, he was a dude who was good at watching movies and telling you his opinion about them. When you double back and figure that places like Kotaku and IGN don't have the sort of patronage that movie reviewers have, but rather rely on prostituting for clicks, their behaviors is completely what you would expect.
