Used: $30,000

Here it is. The rarest of rare. By all accounts, NBA Elite 11 doesn’t even officially exist as a video game. The mobile to console port was cancelled before it was due to release but, in the words of Jurassic Park’s Ian Malcolm, life finds a way, and a few copies of NBA Elite 11 managed to fall into circulation and eventually into the hands of some very lucky gamers. For Xbox collectors, acquiring NBA Elite 11 is certainly possible, but it comes with a major caveat. The only two Xbox copies going have to be purchased as part of a package of five, which together are being sold for $30,000. Basically, you either have to really want NBA Elite 11, or make do with not having it at all.
