Over all four SKU's, Epic Mickey has only managed approximately 410,000 in both NA and Europe. Absolutely dreadful.
If you take away the lead Wii SKU, the three HD versions combined have sold only 190,000.
In addition, with an install base of only 552,000 in the US... The Wii U SKU has managed to nearly equal sales of the 360 and PS3 versions. That's absolutely nutty.
Hard numbers for y'all...
Wii version: 118,000
Wii U: 40,000
Compared to the first Epic Mickey, and even accounting for there being four SKU's this time instead of just one, Epic Mickey has gone from multi-million seller to under a half-million seller, to an install base nearly triple what the original game had only being Wii.
