Lets be real. Kojima loves making these games and he makes a ton of bank and gets acclaim for these games.
If anything he keeps fucking around and experimenting with these games to keep things fresh. Sometimes they work sometimes they dont. He isnt on any martyr mission to piss off the fans enough so theyll stop asking for sequels.
He wants us to ask for more sequels. And mgsv just proves he can advance and do great things with core gameplay mechanics and level design.
Not piss off, educate would be a more apt word. I don't think he's manufactured a way to get fired and become a martyr - though people are going to make him out to be this. I'm not saying he hates the series, there's no way someone would put this much into something they hate. He adores it but wants to get a message across as well. You can call it pretentious or whatever, but Kojima is probably the biggest auteur in video games.
--You get MGS2 which tells you (repeatedly) to stop trying to contextualise everything and let things go, to pass things on for the next generation. Everything about the last 1/5 inside arsenal is a meta-commentary on video games and the culture surround it at the time (among so many other things that the video game industry has clearly ignored).
--People demand sequel to explain what was never meant to be explained. You get MGS3 which was at the time only loosely tied in and had a self contained story. It's pretty grounded compared to the others.
--People continue to demand answers and you get MGS4 which is what people were clamouring for but if you look closely everything has been corrupted in some way - I don't mean this in an overtly negative way.
--Then you get MGSV* which is leaps and bounds ahead of every other MGS in gameplay and the story's big reveal is that you are playing as someone trying to be Big Boss and not Big Boss himself. I need to go over this more (trying to work out the current internal canon atm) and see some other people's interpretations before I cement myself into something - could possibly be Kojima embracing the fandom's desire for more MGS too.
Honestly, I'd ignore all this if it wasn't so heavily documented on the post-modern elements/fuckery of MGS2, but Kojima is insane and seems like this would be his kind of thing. The feelings of people towards the twists of PP feel so reminiscent of those to MGS2, except now there is no chance of a Kojima directed sequel. Or maybe I just never want the Kojima MGS to end and need something to cling to - that's pretty likely.
*I actually had a question I meant to ask earlier, was MGSV ever called MGS5 in anything official?
