Nintendo Recommends Buying Wii Lan Adapter For Smash Bros.

Fighting games move incredibly quickly, so they need to have as little lag as possible, and Nintendo has admitted it knows this. To combat the issue of lag in Super Smash Bros. for Wii U, Nintendo has suggested buying the Wii Lan adapter and hooking your Wii U to the internet that way instead of through Wi-Fi. Some people may groan about having to buy another thing just to play the game online well, but I personally am glad that players can squeeze some extra value out of their old Wii Lan adapters.
