I can play my PS3 safely if I turn my internet connection off right?

I just wish the MassEffect2 DLC was out today so I had something else to play.

I have all the other consoles but I only have new games on the PS3, and I don't want to spend money on a 360 or Wii game since I'm already dropping over $120 this month... -_-

At times like this, I wish I was in the Starcraft2 beta.
