Maaaaaaan. I guess.
I just love ninjas so much. And know this...
While playing Ghost of Tsushima, I will be referring to myself as a ninja throughout the entire game.
I'm always begging the world to bestow upon me a grounded ninja-stealth game set in a realistic feudal Japan, so I guess I'm just desperate to get that kind of direct validation from Sucker Punch themselves even if that's not the main goal of the game's design.
For someone who claims to love ninjas you don't seem to know what they were :p
Main character of GoT is a samurai who uses stealth tactics.
Ninjas were real but pop culture was heavily influenced by Japanese plays that romanticised them. Similarly to how real life cowboys were nothing like westerns make them seem like.
