NBA 2K9

As of December 1, 2010, this achievement and the other online ones for this game are still attainable.

The best way to go about this is to find a boosting partner and do these with your 5 wins in a row achievement to knock out 5 ranked wins, 5 in a row, 3 in a row, 1 ranked win achievement all at once. You should pick a custom ranked match and then pick Street ball. If you and your partner both hit A when prompted to update rosters at the same time, chances are good that you will wind up in a match together. If not, then quit out and keep trying. You will be playing a 2-on-2 match. Once it gets started, have whoever is getting the achievement score 1 point. Then the other person quits the game. The person getting the achievement will need to select "No" when prompted and the person quitting selects "Yes". Do this 4 times in a row and then on the 5th game, do not quit but play the whole game to 21 points. The person getting the achievements should have them all pop at once at the end of the game.

Now rinse and repeat for your boosting partner. You can keep doing this up to 20 ranked wins as well as long as the last game is played all the way through, it will count the previous wins gained through your opponent quitting.

Or you could just win one game, if you don't plan on getting the rest of the achievements.
