For me, The Legend of Zelda: The Wind Waker. SOOOOOO Many people were criticizing the game for its graphical style and 'Not so hardcore' look and its automatically the worst in the series. You know what I say? You missed out in a legendary adventure.
Wind Waker to me felt like a real adventure compared to other games, (Not Zelda games) sailing across the seas trying to save your sister and stop Ganon, while leaving your friends and grandmother to bring her back. So many secrets in this huge ocean, the dungeons felt huge, the weapons are incredible and the animations can really make you laugh. It doesn't matter if it looks cartoony, look at DMC, everyone hated it because of Dante's new look and I was one of those people, but I tried it and I actually really like the combat in the game.
I am looking forward seeing you guys in Wind Waker HD's Miiverse community.
