i cant tell if the did cause on the gc and ds one you have to click two times just to get a boost

No that's why younger kids fail at Time Trials.

I think they tried to make the game accessible for all age groups.

Maybe. Considering when I went to the Midnight release for the game there was at least 5 Six-Year old kids in line with their moms.

They made it eaiser for casual people.

they should put sth like auto-accel 2 make it easier although by putting automatic drifting, it's a bit easier

It's rated E for everyone so it's for everyone.

No I don't think they made it easier. I like how you can choose either Auto or Manual. You know If you don't want to mini boost then you can choose Auto like I do. I hated on MK DS where almost everyone Snaked, I didn't like it.

They made it family friendly, which is why my friends complain that this game is noob friendly -__-;

Then again, the Wii was MADE to be family friendly...

I don't know if your aware of he game rating or not but it is "rated E for Everyone"
