This was confirmed by Kojima himself.
We’ve known for months that Hideo Kojima is preparing an exclusive game for Xbox. It would be a title that would use the Cloud, with an avant-garde concept. Now we learn from an interview with IGN that this still mysterious project had been rejected several times before Microsoft took it over.
“One of the reasons I’ve been able to make games for 30 years is that new technology replaces old technology very quickly. The project we’ve been working on with Microsoft has been maturing for five or six years. It required infrastructure without previous so i talked to a lot of big companies and made presentations but they thought i was crazy.But finally Microsoft understood the concept and now we are working together on the project including the technology aspect.
JIt’s still hard to know what Hideo Kojima has in store for us. Such an avant-garde project will surely require many years of work to combine theory and practice. Crazy experimenter, as he demonstrated with Death Stranding, we can be sure that this new project will not leave you indifferent.
