i have never had the ps3 connected to the internet. having said that, do all add ons cost money, or are there free ones also? i really want the add ons for MCLA and need for speed : hot pursuit.
some are free, some cost money (it's also different when you're a PlayStation Plus member, which gets you some things for free which other users have to pay for).
Just go online, go to the store, search for the game and the store will show you all the available add-ons. it will also show you if it's free or costs money.
