When Super Smash Bros. Brawl was released, an explosion of users tested the waters of the Nintendo Wi-Fi Connection. Unsurprisingly, a ton of lag and online issues plagued the experience. There has been a strong demand for Nintendo to fix the issues with Brawl's online modes, and, in some ways, the company has. The spectator mode has been fixed, and options now appear. However, not everything is perfect yet. Instead of looking into fixing more problems, Nintendo has decided to wait out the issues the Wi-Fi Connection has been faced with.
"As with the launch of any online-enabled game, especially one as popular as Super Smash Bros. Brawl, everyone wants to play at once. This puts a strain on the pipeline. We have seen improvements in online play performance every day since launch." - Nintendo spokesperson
