Out of my 26 physical games, 19 are first party (including Bayonetta 2, Astral Chain, the 2 Xenoblades and Pokemon let'sgo and sword)
So that's 73% of 1st party
Reguarding digital it's very much the opposite: of my 14 games 1 is first party for sure and 2 are harder to pin : Cadence of Hyrule and FAST RMX
So that's 14% of 1st party (counted Cadence as one but not fast rmx)
In total, out of 40 games, 21 are 1st party = 52.5%
