Spotted by the fine folks over at Vooks, the above drawing, seen in JB Hi-Fi just perfectly illustrates one of the biggest challenges Nintendo has with the perennially struggling Wii U: the mainstream audience that adored the Wii simply doesn't know that the Wii U exists. And, if they are aware of its existence, they find it difficult to tell the difference between the two.
This drawing didn't go up in accident. It's clearly gone up in response to numerous consumers who have either gone up with Wii U games thinking they were for the Wii or vice versa. This is clearly an issue that retailers have to deal with on a daily basis.
For us, yeah, it's pretty hilarious that JB requires a sign to make the distinction. But for Nintendo? It's a problem that they need to deal with pretty quickly if the console is to gain traction.
