This style of basketball is completely unrealistic(but very nice), but is kind of grounded in realism in that some of the moves might actually be possible. The standard rules of basketball don't really apply. There is a shot clock, but no goaltending, fouls, carrying over, or out-of-bounds.First to 21 wins the game, and scoring is done by 1s and 2s. The shoulder buttons will give your player "Turbo", but mostly they're used in different 4 button combinations to allow your players to execute dribble tricks and dunks to get themselves open and build up the Gamebreaker Bar.The Gamebreaker is a shot that will net you the standard amount of points, and also take some away from your opponent. (Remember what I said about the standard rules not applying?) So, expect a lot of high-flying, carrying-over, ball-kicking, AND1 video inspiring basketball, only with NBA players and legends involved.(sweeeeeeeeet)
