If you're still encountering issues with the disc, a good method to narrow down the root cause is:
- Try to use another disc on the same console
- Try to use the same disc on a different console
This way you could see if it's the disc or the console.
Some general info:
- PC: If you have a disc or no disc doesn't really matter - you'll always redeem the product code on your account which is then used. You don't NEED a CD, not even to install the game.
- Console: If you buy a physical copy, you can play at whatever console with any account, as long as you insert the disc. If you buy a digital copy, you can play at whichever console you log on with your account and won't need a disc.
