Why don't you just try it and see what happens? This board sometimes, I swear.
Because I won't even be able to download it until Tuesday, when I visit my parents. Internet where I am is terrible. No use in trying to download anything while I'm here. I figured I'd ask away while I'm waiting. --- Placeholder signature so people don't skip the last line of my posts.
You can buy it, and install it with no problem. It will go in Game Data.
Think about it... if you delete the game data and save data of any game, as far as the PS3 knows, you never owned it. You can still download the DLC for it, then the game install adds to the DLC data when you install the game again. --- PSN- BlackRain8782 Now playing: Vanquish- PS3, Super Mario Bros. 2- NES
