I didn't think it through that the CD will get scratched with time the more I play the game on my ps4 :S since the game is waiting for the upcoming updates as well multiplayer and all that with how CP2077 was supposed to be. I wonder if my ps4 is still able to accept me wanting to buy CP2077 as digital from PS4 store? since bought ps4 console like 4-5 years ago I haven't bought any physical copy just the digital copy so anyone know?
If it has gotten scratched, you can do the toothpaste-trick:
Basically cover the business side of the CD with toothpaste entirely:
let it be for a couple minutes (I cant remember exactly, but something like 3-5 minutes)
then wash it off with running water.
The toothpaste essentially melts a thin layer of plastic off the disk, making the scratch to go with it. However, you cant repeat this method many times as the protective layer gets thinner every time.
note that you should use the opaque actual 'paste', not a gel. Also note that you shouldnt rub the disk at all, just cover it with paste then wash it off.
