It might not seem very revolutionary on the surface, but NBA 2K8's introduction of Signature Styles went a long way towards establishing the players on the court as unique individuals and laying the groundwork for the Signature Skills that would arrive in NBA 2K13. Now players not only had signature dunks-which went all the way back to Lakers vs. Celtics-but also dribbled and shot like themselves. Again, it's one of those changes that's so ingrained into the way we approach basketball video games now that it's easy to miss-until you go back and play an earlier game where the only difference in players is their height, with little individuality in how they move around the court.
