You keep declaring victory with nonsense.
Gran Turismo is a SONY IP.
Spider-Man is a MARVEL IP. That’s why the games are called Marvels Spider-Man.
Sony have been given publishing rights for 3 main games.
Sony pays Marvel royalties for each game sale and even Spiderman console bundle sale including the collectors edition console and game.
So using your logic, Fortnite belongs to the entire Video game industry cause of the characters, skins etc.
It belongs to EPIC.
Super Smash Bros doesn’t belong to Nintendo because it has Megaman, Tekken and Street fighters characters in it.
Why are First Party developers called First Party developers? Cause they are OWNED by a First Party like Sony.
It’s the same for games. Bloodborne, Horizon, Gran Turismo, Death Stranding are First Party games because they are OWNED by a First Party. In this case Sony.
You want to see OWNERSHIP of a game? look who owns the IP.
I think you are confusing IP ownership with game ownership here.
Spider-man / Gran Turismo cases.
+ The code, assets, arts, etc are all owned by Sony... Sony's owns the game.
+ The 3rd-party IP licensed to be used as in the game is owned by 3rd-party.
You will understand that when you realize others companies can get the same 3rd-party IP theme and create their own 1st-party game.
For example MS can license the Spider-man IP from Marvel (when the exclusivity to Sony ends) and created another another game owned by MS that will be using the IP... it will be a first-party game to MS because the code, assets, arts, etc are all owned by MS.
You have GT and Forza... they use near 90% the same 3rd-party licensed IPs... they are still games owned by Sony and MS respectively... the use of a 3rd-party IP doesn't mean you don't own the game itself.
And here we reach Lego Horizon.
It is game owned by Lego... the code, assets, etc are owned by Lego.... using the Sony's Horizon IP doesn't make the game a Sony property... just like not make Spider-man game created by Sony a Marvel property.
And I give another example to explain Publishing Rights (that have nothing to do with game ownership).
Death Stranding is a 1st-party game... Sony owns it... and IP used for the game is Sony ownership too... here both are game and IP are owned by Sony.
The game is developed by a 3rd-party developer... so here people sometimes uses this type of deal as 2nd-party.
Sony published the game on PlayStation.
But the publishing rights were given to another Publisher on PC... If I remember correctly it was give the publishing rights to 505 Games.
505 Games doesn't own anything from Death Stranding but they got the publishing rights because Sony didn't want to publish the game there.
Maybe Death Stranding 2 will be published by Sony on PC because today they already have a PC Publishing department in house (that dependes how the contract of Publishing Rights with 505 Games was done too... maybe it was for multiples games).
So again Publishing Rights have nothing to do with the ownership of the game or IP.
It just a license you have from the owner of the game to publish that game.
