Uncharted 2: Fortune Hunter Edition. It comes in a giant, signed box (much bigger than shown below). It contains a life-sized Phurba Dagger replica (also much bigger than shown below, a music CD, an art book, the game, and a code for a bunch of bonus downloadable content. It went for as much as $3,000 on eBay. And most of you can't have it, because it's not for sale in stores anywhere -- Sony only made this ultra-limited edition available for specific promotional purposes.

It's huge, unwieldy, and took two months to get a copy after winning one. It's really not worth $3K, but if you try to steal mine, I won't be afraid to pull the dagger on you, despite signing an affidavit stating that I won't.
