It's a shame it was rated that high by Gamespot. It definitely didn't deserve to be rated the best Wii game made so far.
At least until this 1-hour long Wii version hit the shelves with a bang that it didn't deserve.
The replay value of this game is abysmal. The single player mode lasts you an hour or less, you have to UNLOCK multiplayer mode (and even so, the structure of multiplayer mode is disappointing), and to unlock absolutely EVERYTHING in the game, all you need to do is play for around 3 hours.
I'm not going to be entirely negative in this review, however. The microgames at least maintain the charm and wit they had in previous games, but as everything does, the games slowly die out once you complete the single player.
You unlock multiplayer by completing single player mode (not exactly a back-breaking task). The games are fun, providing your willingness to pass a single controller around, which isn't easy with the tiny gaps of time in between games. Often times the multiplayer is extremely frustrating, which subtracts from the party attitude that made WarioWare what it was before. The game doesn't even have the option to support more than one controller, so passing one around is unfortunately the only option you have.
To sum it all up, WarioWare isn't the best place to spend fifty bucks. I made the mistake of getting it. So basically what $50 gets you is one hour of gameplay, a worthless and frustrating multiplayer, and little-to-zilch replay value to go on top of it all. Please take my advice in saying that this game didn't deserve a better ranking than the Legend of Zelda, not even a better ranking than its predecessors. Do yourself a favor and stay away from Smooth Moves. Trust me, you'll thank me later.
