Twitch's meteoric rise from spin-off company to Amazon's most expensive acquisition ever over three years is a gaming success story. But Twitch has also helped bring about other gaming successes by helping their communities connect, including helping a 13-year-old Nintendo title.

Games like Super Smash Bros: Melee , which retained some popularity long past the GameCube's lifecycle, now have a strong base community on Twitch. The Melee scene has surged to new heights on the back of its tight-knit DIY community, and players are flocking to Twitch in droves to share their matches and watch others.

Despite its age, Melee has reestablished itself as one of the world's most popular fighting games, even gaining placement into the world's biggest fighting game tournament, EVO. Super Smash Bros: Melee was played alongside games like Ultra Street Fighter IV and Ultimate Marvel vs. Capcom 3 at the Las Vegas-based tournament in July.

Mashable spent time at a Super Smash Bros.: Melee tournament held in Brooklyn in early August, and got to speak to the professional players and broadcasters who have devoted their lives to the game. Many credit the rise of streaming with helping drag Melee back into the gamer consciousness.
