Finally finished Kojima's masterpiece so I can finally get back to jdoramas and movies. The Quiet ending was good but the final twist bloody sucked. Gameplay-wise, TPP is awesome. Kojima has made an open world game with classic MGS gameplay of multiple ways to infiltrate and capture bases. Though you have to replay maps multiple times, it works because there are so many ways to infiltrate and the game actually gets harder, though I think the difficulty should have spiked earlier. I don't feel like playing any more since I can't use Quiet after the ending.
Edit: after watching the video of the unreleased Mission 51 , fucking Konami robbed us out of the mother of all boss battles with their cut to funding.
