Podracers
Anakin Skywalker rockets to victory as Sebulba crashes and burns...
An ancient and brutal sport, podracing has been refined over the milennia to become faster, deadlier, and more cutthroat with each new generation of fans and drivers...mirroring the gladiatorial combats of old, the sport of podracing draws legions of bloodthirsty fans from all over the galaxy to the Outer Rim territories (which are pretty much the last place the sport is even legal anymore). Malastare is reknowned for its impressive podraces, and the Boonta Eve race on Tattooine is considered by many enthusiasts to be among the best in the galaxy.
It's possible that, apart from the speed, danger, violence, and noise, what attracts people to podracing is the fact that it doesn't take a vast amount of money to be a competitor in the deadly game...instead, it takes ultimate skill and reflexes, and a well-tuned machine, to claim victory. Many sports in the galaxy are dominated by large, corporate-owned teams, but podracing remains largely the domain of the individual and his pit crew.
The long years of refinement in podracing technology has taken the sport to such extremes of speed and lethality that only very few humans are even physically capable of developing the reflexes and observational skills required to survive, let alone win, a podrace. Generally speaking, the sport is dominated by species' of a small stature and possessed of multiple appendages or enhanced senses, and the veteran racers are often venerated as heroes, again much like the gladiators of old.
Of course, there was that Skywalker boy...that little human must be out of his mind...
