Fairy Ring: My Favorite Mechanism

About Fairy Ring, from BoardGameGeek:

A ray of moonlight shines in the clearing. The fairies wake up and stretch their wings. Mushrooms pop up from the ground, forming a circle. The first fireflies start to land. Magic is returning to the forest, and now it's time to prepare for winter... In Fairy Ring, you want to create a mushroom village to house the fairies in the clearing. Guide your fairy carefully, from village to village, through the fairy ring to gather as much mana as possible. You have two seasons to develop your village before winter begins. Each decision counts towards winning the game.
