The Liberty City Stories section of YourPSP.com has recently been updated to reveal the game will feature Game Sharing. For those of you who are not familiar with game sharing, it means you and a friend can share one copy of Liberty City Stories and play at the same time. It is also very likely that the multiplayer feature will also be available during game sharing.
However, is this a huge feature? The PSP has a mere 11mbps wireless network connection, and it surely does not have enough RAM to store the entire game map and everything else encompassed in it.
I guess we'll just have to wait and see how it plays.
Thanks to Scooby for finding this little snippet of information.
