Among the stretch goals announced for Mighty No. 9, Mega Man creator Keiji Inafune's Kickstarter project, was a $2.5 million goal originally set in order to bring the game to PS3, 360 and Wii U. A recent update on the project's page notes that stretch goal has now been lowered to $2.2 million.
Inafune said at PAX Prime that Mighty No. 9's developer is "not familiar with next-gen," explaining the stretch goal's lack of PS4 and Xbox One options. He also added that the game will be challenging like older games were while also being "fair." The Kickstarter project is currently just above $1.5 million, over $600,000 above its funding goal, and will end on October 1.
