I've been thinking about it, and this seems like the only way Kojima would actually be allowed to apply his creativity to games that don't have "Metal Gear" in the title. Don't get me wrong, it's a cool series, but I get the sense that Konami is desperate to have him keep making MGS games, because OH GOD NOBODY CARES ABOUT ANY OTHER KONAMI GAMES BUT THOSE ONES.
But it just seems like a huge bummer that entire decades of this guy's career will be devoted to this one series. Even Miyamoto gets to make Pikmin or Wii Fit or whatever weird idea strikes him. They gave Kojima a shot with Zone of the Enders, but I'm assuming it didn't sell well enough for Konami to have the confidence to let Kojima continue to make non-MGS projects.
I know he is high up in the Konami hierarchy and maybe he has some say in what games he works on, but I still think it would be interesting to see what would happen if Kojima Productions somehow became totally independent of Konami, and Kojima could just work on whatever he wanted.
