"One of the clearest reasons is that the developer, who is developing the core of the production, is Inti Creates, and they're not familiar with next-gen," Inafune told Joystiq during an interview at PAX Prime. "So with trying to learn that technology, with trying to understand a new piece of hardware, to get a new development kit, all of that comes with it an associated cost and all of that makes the stretch goal a lot more expensive."
Inafune, while not alluding to any possibility of next-gen ports for the game, added that the beauty of Kickstarter is that it allows for direct interaction with the fans – to "reflexively" adapt to what they demand. "It allows us to see how excited they are, what they really want, how vocal they are about certain parts and it allows us to, reflexively, adjust some of what those stretch goals are. What we can say is we're always listening and seeing what they say, but it will forever – and this is the way Kickstarter has to be, unless you're going to be lying to the end user which is what we will absolutely not do – it has to be a balance of what the production realities are and what the fans want."
Mighty No. 9, a 2D action platformer harkening back to the classic games of yesteryear, is seeking $900,000 through Kickstarter for its base financing. As of this post it's incredibly close to achieving its goal and will launch on PC through Steam sometime in 2015.
