Yes, you can purchase DLC for games you do not own. But for MOST games, you will not be able to do anything with the DLC if the content requires the game to be purchased.
There are rare times when you don't need the game to purchase the DLC (the upcoming GTAIV: Episodes From Liberty City will not require you to have purchased GTAIV).
You are warning against downloading DLCs if you don't own the game. Even if you could purchase and download it do you think you could play the DLC or otherwise use it.
You do not play that game online except on the PlayStation network as is an exclusive PlayStation game you can not go online without the PS3 unless your game is a PSP LittleBigPlanet game
yes you can if you sign into the playstation network and download a game
It means you can play against other individuals online over the Playstation Network if you both have PSPs with Playstation accounts, internet connections, and the game
You must have a game disc or a game download to play a game on the Playstation Network. You can search for games at the Playstation Store, but I don't think that is what you are asking
no
No they are downloads that must be done with Playstation Home but not for just to get to the Playstation Network. There is of course space taken up in you PS3 harddrive as files are created including the account information. There could be what is called a download each time you get information like your trophies status, but you do not download the Playstation Network and instead download the information needed.
At the Playstation Store if you commit to buy a game you will need money in your Playstation wallet and then you will be allowed to download the game. After downloading the game you will install it. Then you will be able to play the game
I do not believe you are allowed to share games. The PlayStation Network is restricted to members and they have very detailed rules that allow the PlayStation Network to ban you based solely on the decision that your actions were against the rules. I am not talking about exchanging or trading your game discs and only about PlayStation Network Game and Add on downloads
You need a PS3 with an internet connection to the Playstation Network and a Playstation Network account. You also need the LittleBigPlanet 2 game
yes to play on the PlayStation network you need to sign in That allows them to ban people who break the rules
I suggest wallmart, playstation network, or Game Stop.
