Good job.

This is actually a really good strategy to fight against piracy. Nothing would piss a pirate more than being unable to continue in the middle of a game that supposedly doesn't have copy protection.
I didn't realize there was a PC version. Do the graphics look
?
Since your GPU isn't that powerful, I don't think it would look much better on your PC than on the consoles. Batman:AA is quite resource demanding..
I posted some caps in the original Batman:AA thread if you want to see what it looks like with Max effects at 1920x1200 with 16X anisotropic + 4xAA.
It doesn't look that much better IMO since the whole game is so dark. The PC exclusive Physx effects might make a big difference but I haven't played enough of the demo to notice.
Also, 60fps (if your PC can achieve that) didn't cause the game to play much different since the combat isn't very fast and has so many dramatic slowdown moments.
