First-party

From Styleguide

first-party

When a game developer is wholly owned by a videogame console manufacturer, it is referred to as a first-party developer. Games developed by first-party developers are first-party games. Peripheral hardware developed by a console manufacturer is a first-party peripheral.

First-party should only be used as an adjective, and never as a noun. Polyphony Digital is a Sony first-party developer. NOT: Polyphony Digital is a Sony first party.

Make sure it's clear which company a first-party developer is working for, either explicitly or by context. HAL is one of Nintendo's most important first-party developers. NOT: HAL is one of Nintendo's most important first parties.

Example: First-party developers continue to grow by attracting creative talent to stable businesses that offer a higher chance of getting a product to market. The quality of Nintendo’s firstparty products continues to discourage other developers from competing for a slice of a competitive market.

Wrong: 1st party, firstparty, first party, First-party.

Also see: developer, publisher, peripheral, second-party, third-party.
