Why is a game about being a delivery boy so good? Is it the infrastructure building mechanic? Is it the batshit insane storyline? Is it the fact that every mountain is climbable? Is it the reserved use of combat and massive punishments for killing people?
Who knows, all I can say is I haven't had this much fun with a game in ages.
It never clicked for me, but I think I was playing it wrong. All the climbing was annoying. I hated sneaking around things I couldn't see. I hated sitting through four cutscenes to have Norman Reedus make poop grenades.
I'm also a hoarder in games and I want to carry every single thing I see. The game actively punished me for trying to carry too much equipment, even though I'd usually have no idea how much equipment I'd need to take on each trip.
That said I really respect the game for being something I've never played before. It really is a rare jewel. The scenery is gorgeous. I love that you can take a nap and you have a piss meter. There need to be more games like this one despite how much I hate playing it. I love its mere existence.
It was like Kojima wanted to make a game about forming bonds with other players and not one about killing (especially because killing someone means you have to spend 3 hours trecking up the mountain to an incinerator to burn their body before they go nuclear).
