The Wind Waker gave me the feeling of being on an adventure the most, the islands made it feel like I was discovering things, and the treasures in the ocean diffidently added to that. The music I think really helped too, like the dragon roost island, and the sailing theme, and so many others that just made the game have an adventuress whimsical feel to it, the graphics gave the game the same feel. Everything about the game made me want to explore and find things, and made with your sister kidnapped, it really made me want to continue with the story and adventure further
