I like the winter with the snow and the decorated trees, but when you emerge from that and have deep green grass and butterflies and honeybees, it's really nice. And, you get the cherry blossoms. I have to go with spring.
Autumn is so far my favourite because everything is brown and orange and it all feels so... warm. It matches with the theme I'm trying to get my town to be and it's just amazing ^^ I love the mushrooms and just how everything is... slowing down If you kinda get what I'm saying?
Definitely when everything turns green again. Sometimes I don't even realize I'm missing it until it shows up. And thunderstorms! I love that the game throws different amounts of rain into the game. I had the sound off the first time a storm appeared, and the lightning was a great surprise.
Winter! I love how everything looks when there's snow on the ground. Then again I am pretty happy when spring comes around, I start to miss the green a bit.
I like the Spring and Autumn because thats when the trees and grass change the most. I love the Spring especially for when the trees turn pink and theres cherry blossoms are falling
