Mighty No. 9
Judged on its own without any other context, Mighty No. 9 would resemble a mediocre Mega Man-style game. There have been dozens of those, including more than a few in the official series itself. To study it there would not be the most interesting. About the only things I can say for the game itself are that it copied the cheapest difficulty elements (why?) and in everything from plot to aesthetics simply tried to be “as close to classic Mega Man as possible without lawsuits”.
But what is interesting is the ridiculous amount of hype that came around its crowdfunding. Occuring in the “irrational exuberance” phase of Kickstarter and spearheaded by ex-Mega Man head Keiji Inafune, this was one of those “the gaming king came down to make a dream” experiences. This prompted emotion that successful MM-esques like Azure Striker Gunvolt (made conventionally by a firm that had experience on the official games) and 20XX (crowdfunded yet made by an unknown) couldn’t bring.
The result was a ton of stretch goals “met”, feature creep, the project getting out of hand, the mood turning from hopeful to laughable, and then the game itself sinking like a stone when it was finally released. Whether it could have been better or if the expectations were just too great is an open question. What is not is that this was one of the biggest crowdfunding embarrassments.
