What you need to understand is that they all make stuff up, actual research is beyond the means of the average gaming website these days. Even citations don't count for much, when they all just cite each without doing any original reporting of their own.
My point is that the existence of these comments at all on gameindustry.biz is itself an act of editorialising, the moment you have a human trying interpret that chart and offer explanations you have the insertion of bias. If gameindustry.biz wanted to be fair they should've just posted the chart and nothing else but they can't even do that anymore. What we have is Shenmue at 17 and still above Football Manager 2020 in the Christmas season, that's good enough for me.
