First Party title is the one who develops it. The Second Party is the Publisher/Distributor of the product. The First party can choose to Self Publish/Distribute, but that would make them still a First Party. The majority of professionally made games are Published or Distributed by third parties, often for partial or complete funding of the game while in development. The Third Party is the one who you typically buy a game from. But not only ones that you buy a game from. The other form of ‘parties’ comes from not the business side of things but from the consumer side. The deal is between you and who you buy the game from. That could be the developer but more typically is from a digital store like Steam, Epic, GOG, and so on. In that case Steam would be the First Party and you would be the Second Party and if you installed something like Playnite that would be a Third Party Launcher. Then further on you have the “Game Keys” route where the parties change again.
The whole thing is that the “First Party” and so on comes from contract law in businesses that bled into common usage especially with how common First, Second, Third Person was with video game characters point of view, although it is entirely different. Who is First or Third party is entirely based upon point of view and relativity which is why they actually spell out which is which and what they mean by it in the beginning of legal documents.
