I finally got around to playing my NBA 2k11 game online yesterday. Wow. The online lobbies and ranked matches are the worst layout for online play I have ever seen. ESPN2k5 had a better online layout than this. It's absolutetly terrible. I can't wait until NBA Live or Sony starts making there NBA game again. I love playing nba games to play online against other people, but with these lobbies and how you send invites, it's putting me off to nba2k games.
That's actually a big reason why I don't play NBA 2K11 online, because the lobbies in 2K10 were atrocious. Beyond that...I'm relatively sure everyone you play online is either going to be Boston, LA, or Miami...and I can't say that playing against those teams all the time is appealing. Plus, the game plays well enough against the computer that I almost don't care to play it on XBL.
People online are straight bitches. Like Moo said, they always use Miami, Orlando, LA, Boston - use a different team for fuck sakes.
