Surprisingly in-depth look at the Fox Engine, Hideo Kojima's design philosophy for MGSV, the story a bit, the context of the releases, etc.
I also recommend his three videos that actually discuss what happened in the game, though I don't know enough to know how accurate it all is. Everything's so absurd and ever-changing in MGSV that when I look back on it I had basically no idea what the greater implications and stuff were even if I felt otherwise during the actual gameplay, that I understood what was happening.
- What Even Happens in MGSV? Part One - Afghanistan
- What Even Happens in MGSV? Part Two - Angola/Zaire
- What Even Happens in MGSV? Part Three - Outer Heaven [END]
It also really makes me wish the Fox Engine's engine was used more. I picked up Ground Zeroes on PS3 since it was super-cheap and see how good it looks on last-gen hardware. Seems like it's just going to collect dust at Konami and will maybe be used for a couple more Fifa games or something.
MGS was one game, MGS2 was two games so I can only assume MGS5 is eight games following fibbonachi sequence.
