They gave it an 8/10 and really seemed to like it a lot.  They also praised the Wii Wheel.

Wow, so soon?
Anyway, thats a good score from Eurogamer. They're pretty tough reviewers.

When does the game come out in Europe?

April 10th or 11th

8 out of 10 boooo Eurogamer. Mario Kart Wii deserves a score over 90% average.

IMO Mario Kart games are more fun than Mario platform games. I love the feeling of beaten people in Mario kart multiplayer especially in person. I am not a huge fan of online gaming not the same feeling as playing real people who are in the same room as you. 

Not so good.

That seems about right from the video's we have seen so far, it looks alot worse then Brawl and does not seem like a improvement to the series which is really bad because i like the MK series.

I don't think I really trust sites that review a game 3 weeks before release. But it's probably about the average score it'll get anyway.

I agree with the review. The lack of multiplayer a option in GP mode is a real downside. Why on earth did they opt to leave this out? On another note, it's good to see a positive response to the Wii wheel.
