Defenders of Dynatron City

In a remarkable bit of serendipity, this game wasn't a hit because you couldn't hit anything in it. Garry Winnick and Steve Purcell set about creating a quirky little brawler for the NES, and they made a comic to promote it. Then they made an animated series to promote it. And people were excited. Then they played the game and the whole house of cards came tumbling down.
