Nu förklarar Fumihiko Yasuda från Team Ninja varför i en Famitsu-intervju:
"I am aware there are pros and cons. For me personally, Ninja Gaiden II was my debut, and so I have a deep feeling for it. But there's another reason for this choice. To be honest, there are only fragments of the data that remain. We couldn't salvage them. However, when developing Sigma Plus and Sigma Plus 2 [for the PlayStation Vita], we got as much of this kind of data together as we could and organized it. Because we use utilize that is the reason why we selected Sigma."
Vad tror du om denna förklaring och hade du hellre velat ha Tomonobu Itagakis originalspel är Sigma?
