I started playing Ghost of Tsushima earlier today, and the flute seemed like a pretty small feature in the grand scheme of things. What the game doesn't tell you, however, is that the flute can actually be used to change the weather on the island of Tsushima.
Playing the flute in Ghost of Tsushima is simple enough: you just swipe left on the DualShock's touchpad and protagonist Jin will play a simple melody. Reading Game Informer's piece on things they wish they'd known before starting Sucker Punch's new game, it's revealed that you can actually obtain certain songs for Jin that will change the weather.
You can do this by collecting crickets around the island of Tsushima. As Game Informer's piece points out, you can usually find these crickets near graveyards on the island, and you can earn new weather-changing songs by collecting crickets as you venture around.
This is absolutely something I would have missed had I not been explicitly told about it. While it might not be the most realistic aspect of Ghost of Tsushima, it's certainly an interesting aspect of the game, especially if you want to change the weather to get a perfect shot in the game's incredibly robust photo mode.
