Changes from Brawl

 * Tripping has been confirmed to not return.
 * Though originally there were plans to include a single player story mode, Sakurai has since changed his mind. It has not been announced what, if any, mode will take it's place.
 * Short movies featuring character introductions, like the ones introducing Villager, Wii Fit Trainer and Mega Man, will take the place of the originally planned story mode cutscenes.
 * The speed of the game will be between that of Brawl and Melee. This is to appeal to both casual and hardcore gamers after the lukewarm response by hardcore gamers to Brawl's more floaty mechanics.
 * The "impact-launch" effect has been altered to a colored light trail indicating which player will receive the point should a KO occur. Additionally a red/black effect will appear when a character is hit by a strong attack and has a high percentage as an indicator that the character will likely be KO'd.
 * Some attacks have been adjusted to prevent a character's back from facing the screen.
 * Many of the characters' moves have been strengthened such as Marth's Shield Breaker and Link's Meteor Smash.

Development
The game was first announced at E3 2011, but no further information was released due to Masahiro Sakurai working on finishing Kid Icarus: Uprising. At the start of 2012 the game was officially in production but new information was not released until the following year. On June 11, 2013, two trailers were shown on Nintendo Direct. One announcing the game and the Villager's appearance and another announcing that Capcom's Mega Man would be a new, playable character. One more trailer was released before the end of E3 2013 showing that Wii Fit Trainer would be joining the game. A couple of weeks after E3 in July, Pikmin & Olimar were announced on the official website. At the beginning of August, Luigi was shown off in a Nintendo Direct video. In September, Princess Peach and Toon Link were announced to be in the game. At the beginning of October, Sonic The Hedgehog was announced to be in the game in a Nintendo Direct video. Marth was confirmed to return on November 7, 2013. Rosalina and Luma was confirmed on December 18, 2013. Zelda was confirmed on December 26, 2013.
