It's the same old fun !
I was curious about the Wii Wheel, so I decided to only play on the Wheel first. In real life I don't have a driver's license yet, but Mario Kart does have one for you! (4 players max. for saving profile. Definitely a plus, because this way you can save your own records)
I was very excited to unlock all characters, I didn\t know which one I'd get, but I was definitely curious about the 'baby generation'. (I go for cute this time. But I got annoyed by Baby Mario, don't ask me why.)
(Also a plus if you have Mario Galaxy. You'll see why ;) )
Next up the races. Their all very impressive and very well done (graphics). Not to mention I quite like the bgm. I enjoyed the old races too (the ones they took from the DS, N64 and so on)
Also the new races tend to get my attention and turns out to be one of my faves (Koopa Cape & Coconut Mall are definitely a lot of fun)
As to the ghost trials you can defeat all over the world, this is also a plus. I like to have a 'goal' in a game and Mario Kart has made this possible for me to do so. I enjoyed the wins & losses; I can see now there are millions out there who are enjoying Mario Kart as much as I do (and are so much better than I am)
I also played the battles a lot of times. I also like how they kept the old 'battlefields' but did change it a bit. (Like the one with the blocks.)
So in terms of change from old to new, I think the battles did a better job than the races. But then again, the online thing beats it all. This might be one of the reasons you should go get the game.
There's no complaints about this game so far. I like unlocking cars/bikes & characters. I like to defeat people all over the world.
BUT (There's always a but) in the end I hated the Wii Wheel. Since I started off first with the wheel, I didn't have any problems with the control. Though I always thought the control could be a bit better, like when I have to turn. So, I decided to play without the wheel, I seriously don't recommend this. It was just a crazy moment I have and I thought it might be same similar feel to the Wii Play with the cow race.
But that's a no-no too. So I played with the Nunchuk and now my driver's license show that I use the Wii Wheel for like 52% ? So I'd say, Nunchuk is way better and that way the cord of the controller won\t ever slap my face again.
Overall ; a game I definitely recommend to the Mario Kart players and all who own a Wii. You'll love it!
