CGD: Awesome Video Game Data 2017
I follow the GDC (Game Developer Conference) channel on YouTube and, just right now, I recommend you to do the same. A great number of excellent talks (of course there are some exceptions, like the lame at-the-time-GDC-board-member Peter Molyneux making plain simple propaganda).
There is one that I just watched and is very eye-opening: it’s the annual talk from the guys of EEDAR (a data consolidation company) presenting numbers of the whole industry. There are talks about prices, sales, regions, and mobile/pc/consoles. Everything!
It is a must-see.
