I've been playing Super Smash Bros. for the Wii U. There's this great website called Anthers ladder (smashladder.com) where you can play Smash 3ds, Brawl, Wii U, Melee, or Project M with other players using tournament style rules. You agree on stages, counter picks, it's the must website for competitive smash players. I personally find it better than for glory as for glory stunts your growth in the game. Playing final destination/omega stages trains you to be only good at those levels whereas tournaments have a set of stages to pick and counter picks. I would love on getting into how final destination only isn't really fair and makes no sense, but that's a discussion for another thread.
