This game is good while it lasts but fails to deliver on the key factor
The gameplay is what you would obviously expect from a Warioware game. You have microgames to complete to clear levels. However, the key factor now is the Wii remote. There are many different ways of using the remote. This is a very inventive use of the remote. However, this can all get a little confusing. It tells you which position to hold the Wiimote before the microgame starts but some microgames need more than this and a short one word explanation to fully explain to you what you have to do. Sometimes the game throws you into a microgame and you have no idea what you are doing.
The graphics are actually full 3D this time around and is good to see as all previous Wariowares have all been 2D. In 9-Volts microgame collection you play microgames based on full 3D Nintendo games suck as Wind Waker and Metroid Prime. In these microgames the graphical level is exactly the same as the actual games and you wouldn't be able to tell the difference between this and the actual game.
Now here comes the key part. The Multiplayer. Wariowares key asset. The Gamecube Warioware had one of the best multiplayer experiences on the Gamecube, with loads of different modes and everyone holding a pad, hectically pressing buttons. You would think "Well, all Nintendo need to do is do the exact same formula as the Gamecube version. With the Wii versions minigames it will already be much better". But guess what? They mucked it up. Big Time! Instead of everyone holding a remote each, one person doing a microgame and others trying to put the player off or make a balloon bigger to make the player lose, they replaced it with "pass the remote" multiplayer. This is a huge disappointment as the hecticness of the multiplayer has gone and is no longer the hugely fun and crazy multiplayer it used to be. This is very disappointing as this is the main element of Warioware and is the one part which will boost up its value, as the single player is insanely short.
Warioware is a solid game. You have fun while it lasts. But the one key factor that will have you coming back for more, the multiplayer, has been ruined making this not the essential purchase it should have been.
