I have a copy of MGS in fair condition. Plays fine but is a little scratched. What do you think i could get for it? I've also got access to Conkers Bad Furday for N64 and i understand that's rare too, any info on this? my buddy is shipping to basic and leaving all his retro games with me, i dont really intend to sell them, except maybe MGS wich is already mine, but im just curious.
