It makes sense for people to have Internet connections to play online games, but for offline games there are many countries that we saw [that] do not really have robust Internet."

Social is big for us, but we understand there are some people who are anti-social. So if you don't want to connect to anyone else, you can do that." Developers, too, will be able to limit which aspects of their games players can share with the world.
Sony's major next-gen competitor, Microsoft, is set to reveal its new console on May 21. The latest internal memo regarding the next Xbox's online functionality says that some features should "just work" whether a player is on- or offline.
