Hardest Worlds In New Super Mario Bros Wii

I haven't done a level on this world, but I know it will be hard.

DUH! like, you have to get all the star coins for this, so it kinda has to be hard!

Of course it is, even Nintendo agrees.

Well it is the last one, duh

I can not believe my eyes when I see that this world is number 8 on this list. More pain and effort is put into this than any other world by a complete longshot!

the rocks that come out the volcanoes annoy me and catch me off guard a lot

Lots of difficult levels

I couldn't get past the fortress, and that was 10 or 12 year old me. Now I'm 18 and I still haven't beaten the fortress. World 8 however is even worse, because I can't even make it past the first or second level! - Gehenna

I died about 47 times on Ludwig's fortress, and I STILL have to use super guide to beat it!

Difficult but also boring

Yeah I've always had problems with this one

Lemmy is officially a troll.

Man, all of those stages in this world are tough.

It's in the middle

Mountain land you mean. Yeah it's in the middle

Princess Peach would make a very big fuss if we don't complete this world fast.

It's the worst world ever. Ahhh!

Not hard at all. This world is EASY I did it in 1 day! That's right 1 day and the best world is world 4 with Bowser jr 1st battle

Why is this even on the list? Whoever put this here is horrible at this game.

I hate Super Mario Bros. Wii!

I did this in a hour

It's rather easy
