Haven't we graduated to a point in the timeline of humanity where I can install a game on my PC and NOT need the goddamn disc in the drive to play it? That's the WHOLE FUCKING POINT of "installing" it. I can understand needing the disc for a console game, since it doesn't keep any information on the hardware between sessions.
And if you think this "cd checking" is keeping your game from being pirated, I have a secret to tell you:
YOU ARE WRONG.
Bit-for-bit burners and no-cd patches abound on the Interweb, so just make my life easier and stop wasting my time. There's nothing more irritating than having a portable computer (i.e., laptop) and STILL having to carry some annoying bag with stupid CDs with your insipid shit on them. Stop doing this, or I will stop buying and/or playing your games. It annoys me as a PAYING customer to have to deal with this bullshit. So, STOP DOING IT. It isn't helping anyone.
