The original uDraw was an art accessory for the Wii. This made sense, because by definition Wii owners will buy extremely limited hardware for the sake of some simple fun. But that's because Nintendo has three guaranteed top-notch franchises. (It used to have four, but it gave Metroid to Team NINJA, a company that thinks women need concealed-carry permits to cover their breasts. Metroid: Other M robbed Samus Aran of so much dignity, she was lucky she didn't end up in transparent armor.)
Samus idly remembering when her gender was a non-skintight surprise.
The uDraw still managed to make a few dollars. Then THQ went completely insane by releasing it for the Xbox 360 and PS3. There hasn't been such suicidal marketing since the Alamo's "New Year 1836 Half-Price Ammunition for Mexicans" sale. THQ claimed that market research indicated a "strong demand" for these products, which only proved that THQ shouldn't have slept with market research's wife. That year's top-selling Xbox games were Modern Warfare 3, Skyrim, and Battlefield 3. The only color that console's players wanted to paint was red, with close-range shotgun blasts and an enemy corpse.
Marketing a cheap coloring tool to the PS3 crowd was like offering magnetic poetry to stick on the side of a nuclear reactor: Anyone who wants to use such expensive hardware like that isn't allowed near it. They might as well have offered HAL 9000 a Speak & Spell. Over a million unsold units contributed to a company-wide loss of $56 million for the quarter. They would have lost less money if they'd told their CEO to wipe his ass with thousand-dollar bills and locked him in an all-you-can-eat Indian buffet. It would have been a more dignified suicide if they'd performed seppuku with a banana and a kazoo soundtrack.
