I don't really like competitive smash. I like to see smash as a crazy 4 player party game with items on. The Smash community has really gained some serious steam since EVO2013 though.
The biggest Smash tournament of the year is taking place right now in Vegas at EVO2014. Live stream available on TwitchTV
I'm pretty sure Brandon (has loads of IGNs with Merk) used to be one of the best players in the world(?)
