I bought it the other day, much better than I was expecting.
Most reviews have kinda slammed it because it's now even more accessible.
The only thing I think is a definite negative is the weapons have gotten entirely out of hand now, nintendo needs to include options to disable specific ones or all items in general.
Bikes, Tricks, even the new drifting are a-okay in my books
and online is great.
downloading ghost data is really cool, some people are crazy at this game
(download the world record for grumble volcano)
