SSBM meaning in Sports ?

Super Smash Bros. Melee is a 2001 crossover fighting video game developed by HAL Laboratory and published by Nintendo for the GameCube. It is the second installment in the Super Smash Bros. series. It features characters from Nintendo video game franchises such as Mario, The Legend of Zelda, Star Fox and Pokémon. The stages and gameplay modes reference or take designs from these franchises as well.

Melee includes all playable characters from the first game and also adds characters from franchises such as Fire Emblem, of which no games had been released outside Japan at the time. Melee's gameplay system offers an unorthodox approach to the fighting game genre, with a counter that measures damage with increasing percentages, representing the knockback the character will experience, rather than a depleting health bar seen in most fighting games. It builds on the first game by adding new gameplay features and playable characters. Following the popularity of its multiplayer gameplay, Melee has been featured in many competitive gaming tournaments and is one of the most popular competitive fighting games. It was first released in Japan in November 2001, in the Americas in December 2001, and in Europe and Australia in May 2002.

Super Smash Bros. Melee received acclaim from critics, earning praise for its visuals, simple controls, gameplay, and orchestrated soundtrack, as well as several awards and acknowledgments from various publications; it is now considered one of the greatest video games ever made. It achieved strong sales upon its release, becoming the GameCube's best-selling title with over seven million copies sold by 2008. Super Smash Bros. Melee was followed by Super Smash Bros. Brawl for the Wii in 2008.
