Two years old but discs are weird. I have a galaxy 2 disc that is scratched. got it resurfaced and everything works but a single star. Depending on wear the scratches are/how deep certain things may not work.

Keep in mind as well that on discs (At least Wii games) there's data layers under the graphic as well. So there may be scratches you cant see.

Would recommend getting it resurfaced if you can. This can also help load times if you plan on running!

Dude both youtube POVs are there
