PS3 Needing Disc to play?

[Bahd_Monkey]

I'm on PS3 and it only needs the disc to install the game and register it. After that you don't need to have the disc in the PS3 to play. You don't launch the game from the disc after you install it, you just launch it from your games folder. (You probably already know this, but I'm just mentioning it to be sure.)

The only thing I could think to check is if your son's hard drive is full. If it is then there may not be enough room to install the game and the updates.
