Kojima's a perfectionist. Konami is a Japanese company. Makes sense.
I'm very glad that he worked with them for to make Metal Gear, but considering all the tech advances, they probably should've realized Koji was going to want to go over the top with his final title (as he does with literally everything) and reign him in if necessary, which they clearly did not do (at least, effectively). I know everyone says "Fuck Konami", and for the part of them that took out his name of the game and KojiPro, yeah, absolutely. But this is more of a business decision for them. Kojima is better of being his own boss, this much is clear. I hope he goes on to do fantastic things with another studio, or, even better start his own and be independent, like Platinum.
Hell, this is like the best example I can think of of video game companies needing to rethink their development structure. People have talked Hollywood style, and honestly, this whole Kojima affair seems like a great argument for it.
