Even compared to other niche Wii U games that were published by Nintendo, The Wonderful 101 both had a relatively small launch shipment and a bit sellthrough percentage. The Wonderful 101 was literally the worst performing Nintendo-funded Wii U game that Media Create has tracked (we're not sure how the game compares to Devil's Third, which was sold exclusively through Amazon in Japan, so maybe TW101 is not the worst, but #2 on that list).
Sushi Striker: The Way of Sushido had a similar launch shipment when you combine the Nintendo Switch and Nintendo 3DS versions, and both versions have already shown a higher sellthrough rate after only one calendar year than The Wonderful 101 did after four. In terms of gross retail revenue, Sushi Striker was less than 10 million yen (~$90.000) behind The Wonderful 101 (we're talking ~120m vs ~130m yen here), and it has most likely surpassed The Wonderful 101's gross retail revenue sometime last year. That's how bad of a job The Wonderful 101 did.
Unfortunately, we don't have a lot of data from other regions to compare. We know the game entered the charts in the UK at No.22, which is not great at all. Not even worth a mention in other sales reports, so I guess that says enough. I wish PlatinumGames a lot of good luck with their Kickstarter campaign. Just wanted to show everyone that The Wonderful 101's miserable commercial performance was not just a matter of being a Wii U exclusive; even by Wii U standards, the game was a big commercial failure.
