In Ghost of Tsushima, protagonist Jin's actions will actually influence the weather--and we don't just mean when he plays his flute, a mechanic which allows you to switch between sunny, foggy, rainy, and storms whenever you want. No, how you choose to fight the Mongols will change the weather as well.
In an interview with Ghost of Tsushima creative director Nate Fox, he told me, "The game is definitely scripted to provide more storms as you do things which are extremely Ghost driven."
