Nintendo announced that on September 30, 2016, they’re ending the service for the online multiplayer mode “Regular Tourneys” in Super Smash Bros. for Wii U.
After September 30, the Regular Tourneys will no longer be available, and players will see a blank spot where it was before. The Regular Tourneys are pretty much like the Tourney modes from past Smash Bros. games, except they’re all run by Nintendo. The “Normal Tourney” feature, which lets the community organize their own tournaments, will still be available.
