From reddit:
Summary:
-From his Intro, he sound like he played all the mgs.
-He consider TPP less "crazy" than the previous "or cryptic and elitist"
-He then say for the first hours he was completely into it. That it's rich and polished.
-But then he started to have feeling of weariness and repetition. He say it's linked to: the way this game is, the open world not really mastered and a "diluted" narrative.
-While you don't need to go to mother base, you absolutely need to take time to manage it.
-Non lethal weapons take a lot of time to unlock while lethal one come much faster but are useless (because you absolutely need to improve your base)
-You can get "stuck" in the main story because in multiple case you need to unlock a specific gadget. This can cause some annoying "leveling". He say in PW it wasn't a big issue but here repeating a mission take much longer because of the map size.
-The PW mission system in an open world isn't that good: It make missions much longer, and the map size is "underexploited" with just some plants and animals to fulton here and there.
-The game revolve around camps infiltration, it lack of variety. But of course you can vary your approach. He say Witcher 3 and Arkham Knight have more type of activities. He acknowledge MGS isn't supposed to be a jack of all trades but...
-but that MG game are built around their stories. And here after a magnificent start cut-scenes get sparse and the storyline is shady until the end. Even with the whole puzzle he had trouble getting what this was all about.
-He say maybe there is a true end to unlock that could explain stuff to hardcore fans. And that the storyline still progress after the end.
-You can unlock harder variations of existing missions with specifics challenges (no weapon, no alarm,...)
-He say that the game was "fascinating" (©Spock). Even with "only" infiltration it's fun, especially if you like to experiment and are curious.
-Gameplay time was: 55% of infiltration, 15% of rage against himself or the difficulty, 5% of cut-scenes and 25% of Mother Base menus.
-After 2h he finished the prologue, after 20h he got a bit stuck because he didn't develop MB enough. He saw the end around the 45h mark and played at least 50H.
-You can't use every abilities of your sidekicks from the start (linked to their trust), they become more useful with time.
-Game is constructed in "episode" (1 per mission) and seem to be made to be played slowly. Which he think is why they worked more on the "infinite gameplay" than on the plot.
-He think maybe Koijma is trolling us with the plot and only some select few will unlock the answers. Or maybe he just couldn't make it the last.
-He imply the trailers spoiled too much interesting stuff
-GAMEPLAY (4/5): He said it has the best manoeuvrability in any MGS, with a lot of possibilities but implies some are dispensable (so hum, 4/5 because it's a lot to learn ? It's true this could be an issue for average players)
-GRAPHICS (4/5): Game is clean but he think it suffered a bit from having to be released on previous gen (on a personal note I think they had to make choices because the new gen hardware isn't decent enough to allow clean 60fps without sacrifices).
-SOUND (4/5): He basically liked it. And there is a lot of 80s tracks.
-LIFESPAN (4/5): >40h but he repeated he felt weary after some time
-CONCLUSION: Rich gameplay, repetitive missions, story that promise an lot but doesn't deliver much. Good game but difficult to figure out. "Kojima's last enigma ?"
