There are lots of data, the document in itself is a synthesis of differents aspects.

I think the 1st chapter is the most interesting in vgchartz context (chapter 2 is profiles aspects of french gamers, chapter 3 presents behavioral aspects on the practice and purchase of video games, and chapter 4 a reminder of S.E.L.L missions).

Top 20 2018 games sales by platform and by volume are Switch (11 games - 2,980,730 total units sold) / PS4 (8 games - 3,321,916 total units sold) mainly (and just 1 Xbox game in this top with FIFA 19 rank 15 with 185 780 units sold).
