Sometime in the past 5-6 years, 2K's NBA series snatched the crown of the best sports game and refuses to give it back. The series boasts unmatched graphics, career mode, commentary, and pure gameplay.
The caveat with the NBA series is that it's far from easy to just pick-up and play. The controls for the game are deep and quite complicated, unlike EA's Fifa, and that can be a barrier to entry but for those who take the time, find incredibly diverse gameplay that offers many hours of replay value.
The devil is in the details, as they say, and NBA is unrivalled. Every team plays exactly like their real-life counterparts, the crowd looks fantastic, guest-commentators keep things fresh, and many new and tweaked gameplay modes, are the reason NBA 2K17 retains the crown of best sports game.
