Super Smash Bros. for Nintendo 3DS and Wii U

Super Smash Bros. for Nintendo 3DS and Super Smash Bros. for Wii U (colloquially named Super Smash Bros. 4 and abbreviated as SSB4) are the upcoming fourth installments of the Super Smash Bros. series being developed for the Nintendo 3DS and Wii U respectively. It is a sequel to Super Smash Bros. Brawl, in which Sonic made his debut in the series. Like previous games in the series, they are being developed by Sora Ltd. along with Namco Bandai and directed by Sora Ltd. founder Masahiro Sakurai. On June 2012, it was announced that Sora Ltd. is working alongside Namco Bandai Games in developing the games.

Development
Prior to the official announcement and trailers in 2013, Super Smash Bros. for Nintendo 3DS and Wii U was announced in the E3 (Electronic Entertainment Expo) during 2011, however, the title name was not known and no information regarding to the game was announced, as Masahiro Sakurai was still developing Kid Icarus: Uprising. He also stated that a Nintendo 3DS version of SSB4 will be released as well, have more changes in SSB4, and also have dual support for the 3DS and the Wii U. Sakurai also wanted to make the gameplay experience better than its predecessors. And after months of development, it was confirmed by Nintendo that the first screenshots and a trailer of SSB4 will be show during a 2013 E3 edition of Nintendo Direct.

In the Nintendo Direct of E3 2013, Mega Man from the Mega Man series by Capcom was announced as the guest character of the series (and the third third-Party Character, after Sonic and Solid Snake, to be in a Super Smash Bros. game). They also announced newer characters such as the Villager from the Animal Crossing series and the Wii Fit Trainer from Wii Fit. During a Q&A with Masahiro Sakurai, during the 2013 E3, it was revealed that both games may not come out at the same time. It was also revealed previous characters may not make it due to the Nintendo 3DS's space limitations.

In a Nintendo Direct on 1 October 2013, Sonic the Hedgehog was confirmed to be a playable character,  making this his second appearance in the series since Super Smash Bros. Brawl. Windy Hill from Sonic Lost World is also recognized to be playable as his home stage in the Wii U version. Sonic retains his ability to transform into Super Sonic as his Final Smash and he now shouts "Super Sonic Style", using a clip from Sonic Generations. Shadow the Hedgehog will once again appear as an Assist Trophy using Chaos Control to slow down the user's opponents just as he did in Super Smash Bros. Brawl. Eggrobos will appear as enemies on the 3DS-exclusive mode Smash Run. Green Hill Zone from Super Smash Bros. Brawl is confirmed to reappear on the 3DS version and his home stage in that version. Tails, Knuckles, and Silver reprise their roles as cameos in Green Hill Zone.

Console Differences and Similarities
Due to the hardware capabilities along with other such hardware used in the 3DS and Wii U, there is many differences with almost everything in the game.
 * The game will be released separately instead of the same day so more time is done to make the game as complete as possible. The 3DS version will be released in Sptember 13, 2014 (in Japan) and October 2-4, 2014 (for the rest of the world) while the Wii U version will be released by the Winter of 2014.
 * All of the playable characters in the game will be on both of the consoles. However, all of the stages will be different on both versions of the game. Some may include different stages (such as Green Hill Zone for the 3DS version and Windy Hill for the Wii U version, both of which came from the Sonic Franchise) and some are different due to the different textures, designs, etc. used in both versions
 * Playable characters will run at 60 frames per second (fps) on the 3DS version, even in stereoscopic 3D, while some of the Assist Trophies and Pokémon (such as Meowth) in the 3DS Version will run at 30 fps. All fighters will run smoothly so it won't affect gameplay.
 * Both versions will offer online multiplayer by Wi-Fi, though it is recommended for Wii U users to use a Wii U LAN Adapter for smoother online play.
 * There are two musical pieces on a stage on the 3DS version while the Wii U version brings back "My Music" from Super Smash Bros. Brawl, which allows players to set how often a song will play on each stage.
 * In addition, the 3DS version will also allow the player to listen to music while on Sleep Mode. Pressing the "L" and "R" buttons can be used to skip a song.
 * Smash Run, which is a battle mode where it allows up to four players to search in a dungeon with power-ups, is a 3DS exclusive and will not be on the Wii U version.
 * The Wii U Version will support Amiibo figurines which will give individual character data and stats for the figurine and it can be exchanged to and from a figurine. A stand that transmits Amiibo data to the 3DS will be released at the same time as the Amiibo figures themselves.
 * The 3DS Version allows players to buy trophies that they cannot earn using "Play coins" or "G". It is unknown if this system will be used in the Wii U version at this time.
 * The 3DS Verion will support four-Player Multiplayer as for the Wii U, having up to eight Players.

3DS Version
The 3DS Version has received generally positive reviews. Much of those include a high rating of 93/100 from Famitsu and a 9/10 from Destructoid and among others. Most of the critics praised for a diverse roster, the amount of unlockable features and characters found in the 3DS version of the game, and also, the number of modes that are available to play in the 3DS Version as well. However, there is some things that the Critics may not like in the long term as well. Some criticized about the lag while playing multiplayer, Smash Run and for some, some does criticize the controls in the games while some praise it. The worst reviews that came for the 3DS Version was from GamesRadar which game it a mediocre 3/5 due to the "latency problems in local multiplayer".
