Smash Back Room
The Smash Back Room (formerly the Melee Back Room; also known as the SBR) is a protected forum on SmashBoards. Only members that have shown considerable knowledge or skill (either by posting intelligently or by tournament placement) are permitted to read and post in this forum. The Smash Back Room is most famous for producing a North American tier list, and for releasing suggested rule sets that tournament organizers often used in an effort to keep a standard play format across all regions.
While the Smash Back Room is often criticized for its lack of openness and its exclusivity, it is still the de facto "governing body" of most of the competitive Smash community in the United States, Canada, and some other regions. Their tier list is held in the highest regard by the professional community. However, the rule list has met with issues with different areas complaining about the stage list (either it being too liberal or too conservative). This has happened a lot more often with the Brawl list in comparison to Melee. There have also been issues more recently with other parts of the ruleset; specifically being the amount of ledge grabs allowed (mostly as an Anti-Meta Knight rule) and what should occur after a timeout. The stage list issue has been addressed partially by the creation of a separate group, the Unity Ruleset Committee (formerly the BBR Ruleset Committee).
The 4 Smash Backrooms
BBR: Smash Backroom
Also known as SBR-B, or Smash Back Room-Brawl, this backroom designed the Brawl matchup chart and the tier list for the community. It originally designed the stage list for competitive play. Membership applications are approved by either Marc, Hylian, AlphaZealot, or Shaya. AlphaZealot is the head of BBR for AllisBrawl members who apply, while Marc is the head of European applications.
MBR: Melee Backroom
Also known as SBR-M, or Smash Back Room-Melee, and originally named SBR (Smash Back Room) prior to Brawl, this backroom was the original backroom which inspired the Grimer avatars. Membership applications are approved by either HyugaRiodeau, Cactuar, unknown522, Slhoka, or Marc. Slhoka is the head of European MBR applications.
64BR: Smash 64 Backroom 2012-2013
Also known as SBR-64, or Smash Back Room N64, this backroom is named for the N64 symbol, which members use as their symbol. Membership can be approved by either Surri-Sama, SuPeRbOoM, asianaussie, or cheeseball341. Alternatively, the members were approved by the head of the Backrooms in general, Marc, but this was much less common. Outside of the moderators, the (once) members are listed here as well as below
4BR: Smash 4 Backroom
Also known as SBR-4, or Smash 4 Back Room, was officially announced on November 13th, 2015. It is currently being led by Camalange, Neo Zero, and TheReflexWonder. The many members of this backroom will be managing community patch, voting on tier lists, and creating standardized rulesets for Smash 4. Once the group outlines project plans and establishes direction, it should continue to grow in size. Many well known Smash 4 community members are already established as members of the room. The first official tier list can be found here
History and Closures
The main creation and impact of the backroom were a proper ruleset which was as a ruleset for online and offline tournaments for the next several years. Otherwise, an online ladder; which closed later due to inactivity; as well as the start to a Matchup Chart were made.
Unfortunately, the initial backrooms closed several months later due to excessive spam by the members. This was shortly and abruptly after a new application process was made on Smashboards. BRoomer member KoRoBeNiKi noted that the backroom, while useful, was similar to a social thread but without many moderators. It was "swept under a rug" and is rarely referenced as an old in-joke by former members. Later ideas of creating a new backroom were made, which resulted in the creation of the Sm4sh BR.
