In only its second year, the NBA 2K franchise took a quantum leap in both options and quality over what was already a stupendous debut. In addition to allowing you to play an entire season, NBA 2K1 introduced a genuine Franchise Mode, at last giving virtual GMs control over a team for the long haul. It also focused in on the game itself, introducing 2-on-2 and 3-on-3 Street Modes that let you play on the blacktop and it even had a functional if bare-bones online play component. To be fair, that isn't even so much on NBA 2K1 but on the fact that online console gaming was just getting going back in 2000.
