Sega's head of Western operations considers the 360 and PS3 the natural home of Platinum Games' titles. http://www.nintendoworldreport.com/newsArt.cfm?artid=22864 In an Interview with CVG, Sega's head of Western operations Mike Hayes commented on MadWorld and how it fared on Wii. When asked about whether or not he felt that the "natural home" of Platinum Games titles was on the HD consoles, he agreed.
In regards to MadWorld in particular, Hayes admitted that, "Critically it got a lot of acclaim, but commercially it wasn't the success we wanted it to be. Clearly that was a mismatch with the Wii audience - particularly in terms of the amount of cross-ownership between Wii and the other home platforms. If you're going to play a mature-rated game, you're going to get your 360, PC or PS3 out to do so. But you can't knock us for having a go."
Hayes added that since "Platinum Games is such a cutting-edge developer they need the PS3 or 360 to realise what they actually want to do", noting that the company is "more at home" on those consoles. He went on to say that House of the Dead, as an IP, was more "credible" with the Wii audience.
MadWorld was released in March 2009 in North America, and February 2010 in Japan.
