Unsurprisingly, Melee made it back into EVO and MLG. Good for them.
Unfortunately, despite MLG wanting to add it to their lineup, Nintendo forbid them from running Brawl (read: nothing to do with popularity or competitive merit). Fortunately, there is an awareness campaign on twitter for it.
Melee fans, it's your turn to show that you believe in "one unit". Literally all you need to do is tweet #FreeSSBB, maybe retweet some of the more popular posts while you're at it. Brawl fans payed actual real life money to get a game that wasn't theirs into EVO, even though they had the choice to donate for Brawl instead. All we need from you is a single tweet, mere seconds of your time, at no literal or metaphorical cost to you.
Besides, this is pretty much exactly what Nintendo did to you guys last year. You know how it feels, don't let it happen to others.
