How often is the demo for a game more expensive then the full version? And not just a little more expensive, about 10 times more expensive!
The Twilight Princess Demo on Nintendo DS sold for $301. The full Twilight Princess game for Wii and Gamecube sell for about $30.
Nintendo made a Nintendo DS demo trailer for Zelda Twilight Princess. They only gave it out at E3 to people at their press conference that year so there are probably fewer than 500 of these in existence. The demo cartridge just shows a short video trailer of the game, nothing playable at all.
And as we said is common in our "Rare Games Come in Waves" article, another seller listed their copy on ebay. I'm guessing the price doesn't get quite as high this time.
