Mabey I'm wrong but I feel like there is a lot of story here. It is just presented differently. It is more spread out and the tapes are a must, to get everything out of it. The game wouldn't work if it was presented like past games. This is the first one where I truly feel like Big Boss. It takes time to build an army. Flying into the battlefield and building my army and becoming a legendary soldier works for me in this game. It is PW fully realized. Mgs3 was a great game but Jack felt too much like Dave it was fine for the missions in that game but it wouldn't work for this part of the story and this timeline. I want BB to feel unique, like the ultimate badass and in this game he does. The player has so much agency and it feels great.
I'm liking the story so far and it is definitely the same wacky MG with supernatural characters, political and philosophical undertones, great visuals and awesome gameplay.
