Another puzzle game for the wii you say? Yes, it is another puzzle game, but it's a lot better than most of the other ones. Mercury is a game with you controlling blobs of Mercury and you have to utilize different objects such as a color changing machine or a splitter. Using these different items you must make it to the finish square as the appropiate color and without losing a certain amount of mercury. The game is only $19.99, which was the tipping point for me to purchase this game. It's a good game to just sit down with when you have nothing else to play, or are just really board. The puzzles get harder pretty quickly, so unless you're a stress free person, you will get pissed off sometimes and maybe even throw that wii mote at the screen. You don't have to use the motion control, but instead you can use the wii classic controller, which I highly recommend buying because the game does get rather hard and it's more precise and easier to control the mercury with the classic controller. $19.99, good deal if you don't have a bunch of wii games already.
