The only respectable review is the one with a written verdict, not a one that uses some sort of number system etc. Since the 1-10 scale isnt defined.. for example a game must have X and Y to achieve a 7 etc. So every single review/er has its own definition of what a game has to have for it to qualify for a certain score.
So the only, imo, respectable review/er is the one that uses a written summary of his thoughts of the game.
