There's not usually a lot of difference between consecutive games in the NBA 2K franchise, but NBA 2K24 is doing its best to set itself apart. Installments in the basketball franchise come annually, so it's not like there are major technological advances taking place in between releases. Although they've introduced a few new mechanics and game modes over the years, by now the NBA 2K formula is pretty complete, so not much has been added in recent entries. While new games do attempt to build on the visuals and gameplay of their predecessors, and will occasionally allow players to make minor modifications to rules or play with slightly different team configurations, NBA 2K has remained mostly the same.
