Witcher 2, The - Assassins of Kings Cheats
I agree with you there. But the thing is, you get your backup copy stored on the cloud (GOG.com), so you don't need to worry about damaged discs. And once the game is downloaded (Which is about 14.99 GB), you can directly write it on a DVD and forget about it, unless you plan on installing future updates.
The great thing about GOG.com games is that they haven't made it mandatory for a third-party program to run so you can play the game (Like you do in STEAM/Origin). This is what I want to hear. So you can actually install and play the game on a computer that has no internet connection.
