The crowds received a major makeover and the difference is immediately noticeable - fans legitimately react to big plays by standing up to scream and clap after thunderous dunks or lead-swinging shots. NBA 2K9 goes above the rim with its strong blend of realistic animations, solid controls, and superior presentation. Add NBA 2K to this list of legends, as this year marks the ninth straight year of dominating the ­competition. Nine NBA teams have won back-to-back championships, the best of which - the Boston Celtics of the late '50s and early '60s - won an astounding eight straight titles and 10 in 11 years. It's hard to stay at the top, but basketball teams historically pull it off more frequently than champs in other sports.
