I think his games have been kinda shit post-MGS 3. The dude believes his own hype and puts out the most high school level philosophy story in black goo walking sim and people still praise him as some sort of genius. Seriously the story was so dumb and obvious, the kinda crap you come up with high off your ass. Kojima is Japan's David Cage at this point. Produces crap but people still worship the ground he walks on for some reason.
Yeah, Policenauts was cool. It's the only Kojima game that I played from start to finish.
I also liked Metal Gear Solid 2, but not enough to beat it. Metal Gear Solid V had a lot of problems.
