The king of board games. Perhaps the best game ever released... I honestly can't imagine a game with better mechanics than Spirit Island. Cooperative, not very complex rules but the cards, spirit panels, and mechanisms (and more) elevate the complexity. Incredible combinations that can be made with the cards, spirits, and the island. Each round various countries invade or attack the island of spirits and cooperatively (or solo) the spirits along with the Dahan tribe must face this spread. There is no limit to how difficult/demanding it can become. Because there are many difficulty levels and the backboard increases the difficulty. But it doesn't stop there. Each player can control more than one Spirit and can combine adversaries when you have learned the game well to skyrocket the demands to a cosmic level. The only drawback is the high complexity that results in thinking a lot about your turn.
