First-party developer In the video game industry, a first-party developer is a developer who is part of a company that actually manufactures a video game console. First-party developers may either use the name of the company itself (like Nintendo), or have a specific division name (like Sony's 989 Studios or Nintendo's Retro Studios). Unlike second-party developers, however, the first-party developer is considered part of the manufacturer, not a separate entity, and are wholly-owned by the console manufacturer.

There is no definition of a 1st party IP, so IPs owned by a specific company have always been called 1st party, no matter who develops it.

Well, they've released Sin and Punishment and Metroid:Other M, for example...there's more but I can't remember them now

Ghostbusters the video game is not owned by Sony (which has already been clarified in this thread), but Atari. So no. The Ghostbusters movie is owned by Sony Pictures, completely different.

As far as dicussing this with me, you're being just as stubborn. I'm willing to drop it though, but I stand by my end and anyone adding inFAMOUS and LBP to their lists are fine.

You cite change for one of the reasons why you like the PS3 more... even though it's used the same controller for the last 3 gens..?
