Black Box Challenge is a role-playing game for the Nintendo Entertainment System where players assume the role of a retro game collector. The objective is to gather all black box titles, each unlocking a mini-game that provides power-ups for advancing in the main quest. The game was also released as Jeffrey Wittenhagen's Black Box Challenge, primarily to promote his book Twisted Realities, with only the title screen modified.
A meta NES RPG where you play as an aspiring retro game collector trying to collect all black box NES games. With every game you collect you get to play a mini-game version of the title to earn power-ups to help out with the main game.
A version of the game was also released to promote release of Jeffrey Wittenhagen's book "Twisted Realities: Black Box Challenge" under the name "Jeffrey Wittenhagen's Black Box Challenge". Though the only difference to the game is the title screen.
