I agree with your comment. Kojima has always been on the more eccentric end of the spectrum when it comes to his games, and Death Stranding seems to be no different. His games tend to explore more nuanced themes that may not really resonate with everyone. I, for one, was satisfied with what I saw at E3, and I appreciate the air of mystery that Kojima fosters.
As I have said time and time again, no matter what he showed, there would be someone saying it wasn’t enough. Just like Naughty Dog, Dice and Capcom, Kojima just needs to do his thing and ignore the clowns who just are determined to nitpick a game that is still deep in development to death.
Game looks phenomenal IMO.
