For a game about connecting people, the characters in the open world are truly a void-out of charisma. Might has well have been a silent terminal, I would waste less time at least. Truly awful dialogues, and all the cameos are more immersion breaking than endearing.
Speaking of waste of time, all the repeated cutscenes really needed an auto-skip option. I can't believe I have to skip three (!!) cutscenes everytime Norman Reedus take a shower. It's a bit like in BotW when you enter a shrine but with Kojima's cutscenes lenght. Connecting the network, recycling, delivering the package in the fault, I could go on, they get really old really fast.
Last complain really has to be the combat scenarios: BTs and MULEs have truly a combat system as deep as a puddle. BTs are okaish in theory, but very very samey after a while. MULEs are just a waste of time, they'll charge blindly and easily dispatched with basic tools. From someone that did MGSV, I didn't expect that stealth and basic combat would suffer this much. They are not the focus of the game, that much is clear, but they clearly were an afterthought, could have done without tbh, scrap MULEs and try something a bit more varied for BTs
I trashed the game so far but I will say that the core gameplay is fantastic. The gameplay loop is super addicting, the building aspect of the game, both as a single player and as a community effort, truly stands out as something that will influence developers in the future. It's a bit obfuscated by way too many systems sometimes, I would love to see this "social system" applied to a cleaner, leaner game. To me it's a resounding success, never excepted to like it this much this part of the game.
