In-game items or content that you have purchased may be downloaded from PlayStation®Store. Pursuant to the particular terms of use that govern a specific in-game item or content you have purchased, you may use that item or content on up to three (3) different PlayStation®3 systems that have been activated for your account. You may deactivate or activate specific PlayStation®3 systems, as long as the maximum activated number of PlayStation®3 systems for your account at any given time is three (3).

* The first category, called Network Content, can only be accessed by one activated PlayStation®3 system per day and only by the account through which the Network Content was purchased. Network Content cannot be used on two different PlayStation®3 systems within a twenty-four (24) hour period.

* The second category, called Local Content, once installed on a PlayStation®3 system by the account that purchased it, can be accessed by other accounts on that same PlayStation®3 system.

This means that, if a game is purchased, it can only be downloaded once every 24h, meaning games can’t be shared immediately.

Actually, it doesn't. It means that if someone plays a game downloaded from someone else's account, then anyone else who wants to play that game will have to wait 24 hours after the last person finished playing. One of those types of games is Warhawk.

What about like map packs? Thats installed into the game, so it wouldn't be affected right?

If I had 5 accounts already activated am I safe?
