Estimation of 3DS Software Sales Figures at the end of 2015. FINAL RESULTS!

I think he was referring to the attach rate of Mario games on an install base.

Like how 1/10 Wii owners had a copy of Super Mario Galaxy.
And how 1/5 3DS owners have a copy of Super Mario 3D Land.
And how 1/3 Wii U owners have a copy of Super Mario 3D World.

Notice how the attach rate got noticeably closer and higher with each 3D Mario game (Galaxy 2 being the exception)
And while I do like World better than Land, I still say that Land is a fine game.
