240k WW FW isn't to bad imo, especially compared to Mario 3D World that a) Is part of a much bigger series and b) released in November.
I think its pretty respectable even when compared to DK on Wii which released Nov/Dec on a much bigger install base.
What is AWFUL though and cannot be ignored is the almost complete lack of HW boost. The re-release on 3DS made a bigger impact on HW as did the original on Wii. When you take into account how low the Wii U sales are a % bump should have been easier to obtain.
