So, I've seen threads left and right with the content of: "IDK why Bungie calls it 'competitive' multiplayer, I mean, with all the supers, movement modes, grenades and vehicles, and no custom matches, how could this game ever achieve MLG greatness, so it's clearly going to lose all its audience in the first few weeks, once they've completed the story. More like 'casual multiplayer', amirite?" Bungie calls the Crucible "competitive multiplayer" because strikes, raids, and (if you so choose) story are cooperative multiplayer. Cooperative means you and the other humans you are grouped with are killing not-humans, with a shared goal. Competitive means you and the other humans you are grouped with are given goals contradictory to each other, where at the end, one team wins, and one team loses, and they compete for the highest score. I know some of you folks will be playing in the crucible exclusively, so it's not immediately apparent that there's a cooperative multiplayer as well as competitive multiplayer, but there is, and that terminology is how Bungie separates them. I have no doubt that if private lobbies are not implemented prior to launch, they will be patched in shortly after the crucible proves a stable platform. Chill out, ladies and gentlemen, because until 9/9, there's a whole lot that can change. Stay vigilant, Guardians.
