14Mega Man Universe
In 2010, two high profile Mega Man titles were announced, and by the end of 2011, both games would be cancelled by their publisher, Capcom. One of those titles is much higher on this list, but the other is the arguably more ambitious Mega Man Universe.
its cues from titles like LittleBigPlanet and ModNation Racers, Mega Man Universe was going to take classic MM gameplay and put the tools in the hands of players, allowing for an endless flow of user-generated content. Mega Man fans were going to be able to create their own levels from scratch and share them online, truly living up the title, Mega Man Universe. In addition, the title would feature a remastered HD remake of Mega Man 2 as its core story campaign.
One of 2015's most surprising smash hits was Super Mario Maker for Wii U. Mega Man Universe had the exact same idea five years earlier, but it just didn't work out in the end. Capcom gave the flimsy excuse that the art style and control was not up to their standards, and the game was unceremoniously cancelled.
