If the question was something like, I'm stranded on a deserted island but for some reason i have a tv, ps2, and a generator, but the generator doesn't work, unless I harness some sort of device that will use the reflective surfaces of the ps2 discs, and in so doing will destory whichever discs i use, and I have to choose between destroying my FF discs to play MGS or destroying my MGS discs to play FF, I'd destroy my MGS discs because I think there's more replay value with the FF series, and I enjoy the game more overall.
