It was pretty obvious from the start that you weren't going to be playing as Big Boss himself. He didn't know Russian when The Boss herself taught the Big Boss how to speak it, he also smoked real cigars, not 'phantom cigars' even if they were meant to help pass time. "V Has Come To." Kojima had this planned since MGS2. I thought the story was good. This whole time we learned that Big Boss was planning his resurgence with no doubt the creation of Zanzibarland. If you remember the speech Liquid Ocelot had with Old Snake in MGS4 when they were at the top of his new "Outer Heaven". He was also talking about his recollections with Big Boss when he was helping him with the original Outer Heaven which we now know is Mother Base 2.0 in Phantom Pain. I can't remember which section, but they had even mentioned Big Boss's phantom in MGS4 and the possibility that the body Eva was protecting was probably Big Bosses phantom since the real Big Boss appeared in the end of MGS4 with Zero. What I didn't like about Phantom Pain was Quiet's ending, I had just unlocked her Sniper Wolf equipment but was never able to use it. I only get to see glimpses of it when replaying Cloaked In Silence on Extreme Difficulty. I spent alot of GMP on her weapons only to never be able to use them since they required high R&D levels. Getting the anti-material sniper rifle for her would've helped alot for replaying missions where I had to deal with soldiers in Riot Suits. But there's already a change.org petition going about in bringing Quiet back as a playable buddy. Players are even willing to pay for a DLC that bring Quiet back as a buddy.
