I went to walmart and bought 2k6 today, I have one word that descibes it
AWFUL
ITS AWFUL, I played a regular game and right away HATED it, the way they fun up the court is exactly the same from 2k5, the way they shoot looks like 2k5, the shot stick sucks, the game is pitiful. Wade is rated a 97, Pierce a 92 and it sucks. The graphics look TERIBLE unless you see a replay and u catch a good glimpse of them, the only think I thought was great was while it loads, it goes, Starting at Guard .... at the other guard...at forwar... at the other forwar.. and at center... Then it does a Toyota Key Matchup which looks sick. Other than that it sucks I DO NOT recomend.
Ill rate them:
NBA Live 2005 - 8.0
NBA 2k5 - 7.5
NBA Live 2006 - 9.5
NBA 2k6 - 7.0
Just because it improved (imo) on 2 things unless u can see there face then 3 things, I didnt even bother with the Assosisation.
