I love Kojima with all my heart as a game director/designer for the work he done for Metal Gear (I am a huge huge fan of the franchise), but from a business point of view i think Kojima has great issues
.
Konami created and funded Kojima Productions so that Kojima can produce great games, and after 2011 Konami also funded Kojima to create Fox Engine and go into game license business, and Kojima/Kojima Productions failed to deliver in both fronts
After all the millions of dollars that were invested on Kojima Productions we only got four games (since 2011) that use Fox Engine:
Pro Evolution Soccer 2014 (2013)
Metal Gear Solid V: Ground Zeroes (2014)
Pro Evolution Soccer 2015 (2014)
Metal Gear Solid V: The Phantom Pain (2015)
Also Kojima Productions gave us only MGSV Ground Zeroes in 4 years since 2011 (and some hd remakes and metal gear collections)
And MGSV Ground Zeroes was a failure in sales, compaired with other MGS games
I cannot imagine how much money Konami lost on Kojima in developing Fox Engine and Metal Gear V all these years, especially if we compare it with western studios that deliver a AAA game every two/two and a half years
And I cannot imagine how Kojima will function outside Konami, when he must work (and deliver games) in very strict timetables
