since when is 7/10 bad?

but it is not

87? Better than I expected.

It's weird egm saying the 3d is useless when I've heard a lot of praise of that effect in this game...

The 3D is useless most of the time, so what, its just a visual trick to engage people more, you have a slide bar to regulate it, lowering points for it doesnt make sense.

So it's basically a straight port with a 3D effect?

Could someone list what extras if any are in this, too lazy to check :)

EDIT...

Well here it is from PCMAG..

Donkey Kong Country Returns plays much better when you take all of the Wii controller gimmicks out and replace them with optional 3DS display gimmicks. Unlike the Wii version of the game, the 3DS version doesn't require you to shake the remote to pound the ground or roll—this alone makes the game play much more smoothly. Just press Y, as in the Super Nintendo Donkey Kong Country games. That change improves the game greatly, and makes it much more pleasant to casual players.

Another change to help casual playing is slightly less savory for dedicated gamers, but still useful. A "New" mode lets you play an easier version of the game, with three hearts per character instead of two and more items. The game remains challenging, because Donkey Kong Country Returns was unforgivingly difficult to begin with, so it's a welcome addition for people who pulled their hair out at the Wii version of the game. A limited local multiplayer mode lets players cooperate through levels. However, it doesn't support 3DS Download Play, so you both have to own the game.

if it gets higher than 8.7 thats very impressive even though the original is so well done.!

I think it is useless, but looks good (from what I understand). 

The average score is pretty good for a remake of a game with just 7 new levels. As a owner of the wii game I can only recommend this game, it is fantastic!
