One of the only Wii games to use the hardware to its fullest, a masterpiece.
Graphics: The graphics here are not unlike the ones found in the Wind Waker. The developers have gone to great lengths to create a complete aesthetic of cell shading to suck you in even more. The game is artistically great, and the game will still look good when all the polygon pushing games of today are blurry and muddy tomorrow. The one complaint is that the environment textures tend to get a little grainy when seen up close.
Sound: The sound is pretty good as well. The musical score will yank your emotions from calm and serene to excited or panicked. Some of the sounds will emanate from the Wii remotes speaker which sounds a little tinny but is still a nice touch.
Gameplay: This is one category in which Zack and Wiki shines. The game drops you off in little areas in which you solve bite sized puzzles to claim the treasure at the end. But don't think that this is going to be a cakewalk. Almost anything that injures Zack will automatically kill him unless you have yourself a Platinum Ticket, the games version of an extra life. Another thing is some puzzles seem to be more hit and miss than other ones, and the difficulty differs greatly from puzzle to puzzle. While you are solving these, you will be using the remotes actions to do everything from playing a flute to rocking a baby dragon to sleep.
Zack and Wiki is an excellent game, one of the few that uses the Wii hardware to its fullest. It deserves to be in any gamer's collection and is Capcom at its finest. And remember "I am experiencing déja vu and amnesia at the same time, I think I have forgotten this before.
