Brawl will feature a level editor, SD storage, sharing with friends, and submission for "stage of the day."
Major online features of Super Smash Bros. Brawl continue to be revealed at the game's official blog. Today's update details the level editor, a first for the series. You can choose from various music, backgrounds, and level sizes, then place all kinds of platforms and objects on a grid to create your level. The number of pieces you may use is limited, so that the stage won't become overly crowded. This mode is compatible with the SD card slot, so you can create lots of levels without having to worry much about storage.
But that's not all! Brawl also allows you to send created levels to friends, with the odd stipulation that you must have shared both Friend Codes from the game and Wii system numbers. There is also a Submit feature, much like the one in the Everybody Votes Channel, with which you may send a created level to Nintendo. Every day, one user-created level will be chosen by Nintendo and sent out to Brawl owners via WiiConnect24. These levels will only be available for one day at a time, but you can always look forward to a new level the next day. The blog update also mentions very briefly that Snapshots, a feature previously profiled on the website, can also be submitted to Nintendo. It is not yet known how these might be used or delivered to Brawl players.
