BS on post game content. Yes levels did that but not close to half of them. 

Yes, they did. Just added some new gimmick, but still the same.

These were amazing games but people were constanly whining about them not being like the Galaxy games.

Galaxy did the same and I don't see anyone bitchin' about it.

If you are talking about the comets, yes. The thing is, nobody is saying post story content in the galaxy games are good.

Well, I think post game content in 3D World is better. You get a mix of new levels and old ones with, like you say, some kind of twist and an upgraded difficulty. In Galaxy you get the exact same levels. Only you collect coins this time. Yay...

Both are not worthy. Don't try to justify the 3DWorld one.

While I would still prefer another 64/Galaxy type 3D game, I still really enjoyed 3D World. A lot of great levels, and I loved the cat suit.

3D Land was also pretty good, but I think 3D World is easily better. A lot more ambitious in its level design.

Don't try to pretend you are unquestionably right

3DWorld post-content was challenging and fun for me, I found it perfect for the hardcore fans, sure is less creative than the 8 worlds, that doesn't make it bad.

I don't pretend to be right. I am right.
