To date, The Legend of Zelda: The Windwaker is the greatest game I've ever played.
A lot of people complained about the graphical presentation because of the cartoony look and feel to it, but that only made the game a whole lot better. The open-ended, massive ocean to explore is brimming with dungeons, enemies, islands, treasure, and so much more. The game also has some of the best, most memorable characters I've seen in a game. As you go through the game, the storyline gets better by the second. There is also the ability to pick up weapons from fallen enemies, which is new to the zelda series.
I love everything about this game, and i am currently playing it for the 4th time.
