Sony is hoping to replicate the success of social networks and Second Life with a feature called Home.
Playstation 3 gamers will be able to meet, chat and share content with friends inside a 3D universe.
"It's about community, collaboration and customisation," said Sony's Phil Harrison at the Game Developers Conference, in San Francisco.
Gamers can buy furniture and clothes, while publishers and retailers are also expected to offer 3D spaces.
