I have a complete copy of this game that I bought from a boardmember a few months back and I would not sell it for $475. I think that this will eventually be the hands down most desirable SNES game.

Star Fox Comp may be slightly more rare and more people are probably looking for it, but DKC comp has the advantage of having an original box that is hardly ever included. This is a tough game to find boxed and I think it's a really good investment.
