Damp, lint-free cloth, like a soft old T-shirt, gentle strokes from the inside hub towards the outside edge, NO CIRCULAR motion, just inside to the outside. I've also held disk under a stream of water, gently wiping, and then set them in the center of a soft cloth, folding the corners up to gently wipe dry. Those were disks that my then 4 & 6 year olds got jelly fingers on... You do not want to scratch the disk further. The next thing to do is copy the disk (actually, both of them). You of course need a DVD-R (+R) burner and a blank disk. The +R usually have the best "compatibility" for game disks, which is probably a function of the software actually... If your computer came with a burner, it probably has a recorder app that can "clone" or copy a disk. You might need a lot of error checks while doing it, if the disk is in bad shape. If you have a Linux install, RR and others could point you to some really good stuff. Some programs will read sectors multiple times and be able to get better results than most of the software that comes with drives. Another thing to remember is that drives can wear out, and the laser might be getting weak. If you have a 2nd computer with another drive, you could see if the disk works in that computer, and then go from there...
