Is there any way to put my Unity game on a disc (not a thumb drive)? I tried a lot of times and I need help to see if you can do it or not. Thanks! 
You mean for distribution or just for saving/backing up?
I mean distribution.
Don’t take this the wrong way I’m trying to understand what the problem is but
You don’t know how to burn the files to a dvd??O.o.
Unless you are trying to figure out how to make an installer package that will run off the dvd
