This coming Monday, April 8 is set to be a particularly sad day for Nintendo fans, as that's the day that the online services for the company's Wii U and 3DS systems will shut down forever. Online service shutdowns are a sad reality of modern gaming, effectively blocking players from enjoying the online components in various games, and in some cases, erasing entire games from existence. This isn't the first time that Nintendo has shut down the online services for its consoles, so many fans have been anticipating the same fate for the Wii U and 3DS.
