It has been discovered that Jin's actions in Ghost of Tsushima have an impact on the world's weather. It was previously reported by players that certain mechanics in the game, like playing the flute, would switch the weather between sunny, rainy, stormy or foggy as per the player's wish. Now, however, it has been reported by Sucker Punch creative director Nate Fox that the weather in Ghost of Tsushima does change depending on how Jin takes on the Mongols.
In an interview with GameSpot, Fox said, "the game is definitely scripted to provide more storms as you do things which are extremely Ghost driven."
This is an interesting feature that we haven't seen in many other video games in the past. Additionally, with the way Jin has been portrayed in the game, the feature actually suits his identity and his combat approach. In Ghost of Tsushima, Jin abandons his identity to become the fearsome Ghost destined to take down the oppressing Mongol forces. Most enemies that you encounter in the beginning of the game can be easily defeated with samurai tactics and tools. However, as you progress through the game, you'll face tougher enemies, requiring you to adopt the stealth approach, or the Ghost way.
As you become accustomed to the Ghost playstyle, you'll soon notice that the world around Jin will also begin to match his combat approach. The gentle breeze and sunshine will turn into blustering winds, with clashing thunderstorms and lightning filling the dark skies. As a result, the environment will naturally turn dark, allowing Jin to sneak up on his enemies and dishonorably slay them.
This change of weather is a great touch in the fantastic video game, making Jin seem like a force of nature as he adopts the Ghost way to accomplish his missions. The brooding look of Jin also fits in well with the stormy backdrop, making the game look even more cinematic.
So, what are you waiting for? It's time to ready your katanas and bend the winds to your will.
