Those of you with good memories will no doubt recall Kaio: King of Pirates. The brainchild of former Capcom staffer Keiji Inafune, this 3DS action title was announced in 2011 and was supposed to the hit the console in the following year.

Jointly developed by Comcept and Intercept, Inafune's new studios, Kaio was picked up for publication by Marvelous, which also bankrolled the development costs. The hope was that the game would spawn a multimedia franchise that could cover anime, merchandise and comic books. 

Unfortunately that wasn't to be; the game missed its 2012 launch window and was delayed until 2014, before Marvelous finally pulled the plug in 2015. Unseen64 now reports that the venture cost the company a whopping $3.8 million.

Inafune turned to crowdfunding to produce Mighty No. 9, and Comcept has since worked on other titles, such as Yaiba: Ninja Gaiden Z (2014) and last year's ReCore.
