You are wrong. Again, is Spiderman not a first party PS4 game? Answer that question. Nintendo 100% considers any game they publish a first party game. the meanings of these terms got bastardized over the years when people starting using them as part of console warrior arguments and bullet points.
Spiderman is little weird, and I dont want to talk about Spiderman when we have examples for Switch.
So you telling me that games like Octopath Traveler, Daemon X Machina, Bayonetta 3 and this game, are all 1st party games, same like Zelda, Mario, Yoshi..? That dont make sense.
