Every game on the PlayStation 3 will use the same universal sign-in and the same online ID, Sony has confirmed - even titles which do not use the central buddy list and messaging systems offered by the console.
Speaking to GamesIndustry.biz this morning, the UK producer on launch title Resistance, Dan Brooke, said that he "wishes to be clear that Resistance uses the PlayStation online ID to sign into the game. There is no separate login for Resistance and the online ID you create will be the same you use for all titles."
The clarification comes after Ted Price, head of Resistance developer Insomniac Games, revealed last week that despite having extensive online functionality, the game will not be using the central buddy list offered by the PS3; instead, players will build an in-game buddy list unique to the game.
Resistance is also set to offer advanced community features such as clan support, party support, match-making and ranking. At present the PlayStation 3 operating system does not offer centralised support for these features.
However, contrary to some reports which have appeared in recent weeks, gamers will not be expected to sign up new accounts for each game they play, as the PS3 will handle a single sign-in ID for this purpose.
This system is similar to how online games worked on the PlayStation 2, where users had a single Central Station ID which identified them in every game on the system - although unlike the PS2, the PS3's network adapter is built in and configures itself automatically in most network environments, and the system boasts persistent internal storage for network and sign-in details, as well as for downloaded content.
However, the PS3's service still falls significantly short of Microsoft's highly regarded Xbox Live system, whose voice chat, messaging, buddy lists and so on are not only a core part of the service, but are utilised by all online titles on the console.
