This game looks horrible. I still don't understand Itagaki's mentality. If I was him, I'd use the money I get from this game to make another fighting game, he will regain all his credibility. I know for a fact that it will boost him right back on the spotlight, that's the only successful future I see, plus he'll gain a lot of support from his fighting game fans, other than that, it just doesn't look good for him.
Yeah, the game looks as if it was made via a older generation console before Wii U, and he picked the wrong console to do it too. (Not that Wii U is bad or anything, but this type of idea for a game just doesn't fit for a Wii U.) If anything, he needs to partner up with Team NINJA somehow and help make Ninja Gaiden. (He needs to make arrangements or something.)
Here's some Devil's Third gameplay that you probably(?) want to see. This Wii U exclusive has had itself a rather troubled development period and well, it looks that way.
