It's not just Wind Waker's graphics that have got the HD treatment. The game's best piece of key art - a simplified version was seen on the GameCube version's manual - has been too. For better or worse.
Like the game itself, I prefer the GameCube's more hand-drawn take, but that doesn't mean I hate this. It's Wind Waker art. What's there to hate.
