Not sure if anyone else cares, but I want to start a petition on the NBA 2k11 boards to bring back the NBA Today matchups. I haven't been able to post, however, not sure why (I didn't do anything bad, I promise, I only just made the account yesterday). I'm afraid that they'll take down the server before the issue gets resolved. This is the only achievement in the game that hasn't been available since like June of last year. If enough people comment and email them (which I was able to do, will let you know how it goes) then I think they will do it (just like they pushed the server closures back).
Don't try and be mean when talking to them. Just say that doing so would help their fans and get more people playing in order to finish the game and thus, more likely to purchase their subsequent titles. Hopefully, if people care enough, they will do it the week before the server closes as another show of good faith.
Cheers!
