Games bought through the PlayStation Store will be able to run on five-or-fewer systems. Of course, if you own more than five systems, you can probably afford to pay for the game again on the sixth. (Hah, we kid; you didn' t get so rich by wasting money on a game you already bought.) The important application for the five-or-less rule is that you can log in to the PlayStation Store at a friend' s house and re-download a game for free.

When you leave your friend' s house, Sony says that you can leave the game there. If the title is an online multiplayer game, only one of you can use it at a time. But if it' s an offline game, we were told that the multiple systems can continue to play it.

Sounds like you and your four best friends may be splitting PS3 game downloads.
