Super Mario 3D World given rough 8-hour completion time, but there’s more to see and do

[Ninjahound101]

So i once made a calculation that put 3DWorld's completion time between 7.16-8.33 hours and guess what i was right!!!!

Here it is

maybe something around 64 or sunshine(i didn't play either one of them)
as for the length of the game here's a bit of math:
there is one stamp in each level and between 86-100 stamps according to counting (didn't bother to do it myself) so 86-100 levels each level is about 300 seconds so 25800 seconds to 30000 seconds dividing by 3600 to get the number of hours the results are 7.166 to 8.333 hours of gameplay excluding the commander toad and the enemy levels and assuming you never lose any lives so it should last you 10-15 hours depending on how well you play and whether you want to complete the game or not

But no need to worry the game will also have Captain Toad, Mystery house and the Luigi Bros. levels, but that's not all, here's what TheBitBlock's Josh Thomas who's playing the game for a review said:

I won’t spoil anything, but anyone who has played 3D Land, knows that finishing the game is really not finishing it at all. That’s all I can say.

It’s a lot longer than 8 hours, folks. I can’t really say much more than that, but don’t worry.

Give me your thoughts, how long do you expect the game to last?
