Well, I installed my old Opposing Force CD tonight. It installed fine, but I hate lugging around the disc because it's on a laptop. So I fired up Nero ImageDrive to burn an image to the hard drive so that I could run the game from the virtual CD, but it was getting tons of errors. I took a look at the disc and sure enough, it's scratched up pretty good. Not huge deep scratches, but scratches from not being kept in the CD case all the time. It installed fine but gave me multiple errors when making the image.
