Hi there,

I released the next chapter in the Quantify Me series: Metacritic. Having done an analysis of the CSDb first (CSDb: Quantify Me) in July 2010 and then Mobygames (Mobygames: Quantify Me) at the end of December 2012, the attention has turned to the games listed at Metacritic. This one turned out to big a big analysis, collecting data almost non-stop from the Metacritic website between the 25th of August 2013 and the 10th of September 2013. Then cleaning of the database and actual analyses took another lengthy period of time, as this needed to be done late in the evenings, as much as possible. Finally the first chapter of this endeavor is here. The conclusion of this 30 page paper (which you can get here as PDF) is that their data is really of no use to end users, as the bias in there is large.

I have attached it here for you convenience.

Cheers,

Mike

For the last chart, when you compare the number of games released between Mobygames and Metacritic, I think this type of bar chart would serve you better.
