New Kids on the Block: The Official Video Game was an alleged NES game being developed by Parker Brothers based around the American boy band of the same name likely developed sometime during the group's peak years between 1988 and 1993.
Very little is known about the game, other than the box, which was sold in an auction on ebay for a winning bid of $700. The box was sold by Tracy Baren, wife of Andrew Baren, editor of Electronic Gaming Monthly (although this was before their constant April Fools pranks). When she was asked about the box, she said "Honestly? This box doesn't have much value to me personally." It was sold to Jason Wilson, known as "DreamTR" online.
