Well, I originally meant in terms of availability, but since you point it out, that doesn't really matter to me. It's resale value indeed.
Sometimes when you get on eBay, there's a wide range of prices, or just not many of that item for sale. Okami, for example. I saw one completed for $5 and one completed for $50. The Broadband Adapters, however, rarely show up.
But back to my Twilight Princess, the question wasn't whether it is rare or worth something now, but whether it will be years down the road.
I remember you from the other thread, though, and you were very helpful. Thanks!
Edit: ayb, you're always so helpful. Thanks.
