Well, if you ask me, I would still rate any single department, then to make the rating more personal and subjective, one could give more importance to a specific quality, but with a specific criterion, otherwise it is possible to distort the final score.
In this way it would be very hard to give a 4/10 to games like Halo4, or Uncharted4, etc. So, once the ""Troll or Clickbait"" Review is forced to give a 9 or 10 to a stellar Graphics department, 9 or 10 to the Audio Department, a 8 to the "controls" department, and a 7 to longevity, even if they try their best to downplay the Story and Gameplay with a 4 or 5, still these biased people must do an average among 9 or 10(Graphics), 9 or 10(Sound), 8 (controls), 7(Longevity), their biased 5 on Story and Gameplay.
The Average would still be 7,33, and they could round to 7,5 or 7 according to what they consider more or less important. That would work very well against Trolls or Clickbait who gave Halo4 or Uncharted4 a 4/10. No way a game with great graphics, sound, good controls, can get a 4/10 because the biased review try its best to downplay the Story and gameplay. They must do the average among all the Game department anyway, and if these fools, for example, give 4/10 to the Graphics Department of Uncharted 4, everybody would know even more that those people are a joke and should be banned from Meta or any other Critic Review system.
