For an EVEN MORE realistic experience, set the difficulty to Pro (Which is what most people play anyway) & the quarter length to a full 12 minutes
Having said that, NOBODY here plays in Rookie mode anyway. To be more honest, almost EVERYBODY here plays that "Other" NBA game anyway. Just saying
I play my Nuggets Franchise on NBA Live in the Pro difficulty level (I refuse to play it using any other difficulty level) in "True GM" mode (That is to say I focus on handling the BUSINESS end by making trades & signing free agents & spectate the actual gameplay)
Just ttrying to help enhance your own gameplay experience
Cheers & GAME ON
