This game reminds me of red dead 2 in that the entire appeal of the delivery missions is to smoke a fat blunt and take in the visuals, because otherwise you are traversing very slowly and it will drive you insane over the length of this game. The combat itself looks okay, the mgsv-esque setup is a good base for the mechanics, though if it as infrequent as kojima claims then the world itself remains the game's biggest hurdle.
I wish this game would have a good story, but I've played this man's games for many years and I know it will be a lot of dumb ass shit. I'll still play it.
