NSW - 23 (8 of which are third party)
PS4 - 7 (5 of which are third party)
This was a good week for PS4 third party games, since three new ones hit the charts. In spite of that Switch still has 8/13 = 62% of third party games in the top 30 chart. Even on a good week for PS4, Switch still has a majority of the third party games.
