I have NBA Live 2007, because it's the only real b-ball game for PC. It's great on the PC, I like DLing historic teams and playing. You can tweak everything too, from the ball to the score overlays.
Gil on the cover? Good move!
I've had NBA Live '95, '96, '97, 2000, 2004 and now 2007.
I usually play until I can't update it any further or run out of things to change.
