This is game is the definition of boring. But I'll start with the good things.
. Its design basically made walking fun (for the most part).
. The soundtrack is pretty. Not great, but it packs a nice punch.
. The story is deep and emotional, characters are memorable and everything just feels genuinely original.
. Despite its flaws, the story kept me going and curiosity got me hooked, but I couldn't wait to see the end of it.

As for the bad things... Well, all the rest.
. The gameplay loop starts decent and fun, but ultimately overstays its welcome and becomes overly dull and repetitive.
. The story is great and unique, but MY GOD it is convoluted and tiresome!
. Why does it need to repeat the same cutscenes and messages again and again? It should skip it automatically.
. TOO MANY TUTORIALS! TOO MANY THINGS ON SCREEN! TOO MANY USELESS NEW ITEMS! JUST LET ME FUCKING WALK!
. Unrewarding long and unnecessary sidequests.
. Bosses are a joke.
. From the UI to the information displayed throughout the game, everything just feels... Messy.

Kojima, I still think you're a genius, but you missed the mark with this one, buddy.
