Wii-U tracking here has been pretty good on the whole, then, at least for November.
Only things I've noticed are:
- We have Blops 2 slightly higher than Scribblenauts Unlimited up to December 1st, but NPD has SU higher.
- We have Arkham City slightly higher thank Epic Mickey, but NPD has EM higher.
- We have Assassin's Creed 3 6k higher than both Sonic & Skylanders, but NPD has those two games as 9 + 10 with Assassin's Creed not in the chart.
They're all really minor amounts of numbers though, so perhaps just some small adjustments in the future.
