Ok it has just been brought to my attention after I started downloading my two free games from PSN that I'm quickly running out of storage. After I deleted a whole boatload of Game Data Utilities that I don't use anymore as well as the majority of my saves for the same games, I'm currently at 22GB/74GB. Now LittleBigPlanet is about 2GB and inFamous is about 7GB that leaves me 13GB of storage to put AC: R, Skyrim, Battlefield 3, and probably a few more games on.
So is there a way to get more storage without having to replace my HDD with one that has more storage?
