An unreleased Superman NES game for your enjoyment

This post is a little bit of a history lesson, but at the end you get to play a game, so stick with us. A few years ago, an unreleased Sunsoft game, called Sunman, was uncovered -- and it was pretty clearly a re-purposed Superman game. Now, an even earlier version of that same game (which actually features the Man of Steel!) has been discovered and made available for your perusal.

The gameplay is so-so, but there's an absolutely gorgeous version of John Williams' Superman theme that we just adore. It's worth it for the music alone, trust us.
