Mariokart Wii to me is really fun. I bought it and play it often. Without further ado...here is another game review from www.nintendolife.com There are bits of complaints about the game so I left most of them out. This review was not written by me it was someone elses opinion

To get straight to the point: this game is very, very fun. On saying that, this game also has a lot of flaws that could have detracted from the entire experience. Thankfully for Nintendo these flaws don’t really take any of the fun away, allowing for the negatives to be somewhat brushed beneath the carpet.
Mario Kart Wii is essentially Mario Kart DS blown-up and built upon. For me Mario Kart DS was probably the best game in the series and so this is a big accolade for Mario Kart Wii to earn. The way the game handles is far superior to Mario Kart 64 (which hasn’t aged well) and it also runs a lot faster than the dire Double Dash!! This is a proper game of Mario Kart and the extra 4 characters per race (12 characters instead of the original 8) only add to the kind of mayhem that we’ve all come to expect from the series.
The game comes packaged with the traditional single-player mode, a multiplayer mode (up to 4 players on one Wii console), the Nintendo Wi-Fi Connection mode (I’ll go into detail later) and the Mario Kart Channel.
The single player mode is typical affair with the Grand Prix mode, Time Trial mode and Battle Mode present. As usual the Grand Prix mode is split into 50CC, 100CC and 150CC but there is an important twist here.
Bikes have been included to mix up the gameplay somewhat and although they handle slightly differently to the kart’s essentially they are the same. What is different about the bikes however is the ability to execute a “wheelie”, which allows for a temporary speed boost but a lack of control over the bikes direction. The bikes are questionable addition which has caused an imbalance in the dynamics of the gameplay. Sadly the karts just can’t compete with the bikes ability to execute speed boosts whenever necessary and so it means that anyone playing with a kart should get beaten by the bike.
In the single player Grand Prix: only karts can be used in 50CC, only bikes can be used in 100CC and a mix can be selected from in 150CC. The Grand Prix mode is split up into 8 different cups providing 16 new tracks and 16 classic Mario Kart tracks.
None of the new tracks are particularly memorable with the exception of Coconut Mall and Wario’s Gold Mine – both of which are really outstandingly thought out tracks and thoroughly enjoyable to race on. The other tracks are not bad, just they seem to lack the “Wow” factor that you experienced when you first found Peaches castle in Mario Kart 64 and also drove around Isle Delfino in the GameCube and DS versions. It would have been nice to see the inclusion of some environments from Super Mario Galaxy, Wario Ware or Super Paper Mario but sadly they are non-existent.
The tracks have all been designed with Mario Kart Wii’s other new big addition in mind: the trick mode. Tricks are basically simple moves which can be executed when your kart is mid-air, allowing you to gain a small speed boost when you land. Think Excite Truck and you’ll get the idea. This means that many of the new tracks have been designed with this new trick system in mind and therefore include more ramps and “half-pipes” than ever would have been present in previous versions of Mario Kart. Thankfully the tricks are really fun to pull off and are a welcome addition to the game.
Sadly, when you’re driving around, pulling off tricks and having a nose around at the environments there is not a lot to see. We all know that the Wii is not the graphical power-house that the PS3 and the XBOX360 are but surely the console can deal with better visuals than this.
