I'm sure you already know this. But just wanted to tell you anyway. I got the full DC Universe game on my PC for free. Downloaded and installed it a couple of months ago. Plays perfectly. If you want it for PS3, I don't know if it's on PSN but it should be a bit cheaper now on amazon.

DC Universe is available on the PSN for free download and it's F2P as well, although with limited content (as one would expect). Still, I'll give it a shot til Defiance and Final Fantasy XIV A Realm Reborn come out.
