It's not that you're old, but rather that you're a more demanding and harder-to-satisfy player. The younger generation is easier to please, no need for playbooks, advanced coaching systems, or realism; they just want card drawing, dribbling, dunks, and non-stop three-pointers with ridiculous accessories to put on their avatar. The timing of shooting has become too critical in the game, and it's too simplistic (the shooting system was decent in 2K21, but it needed refinement).
In short, take a look at the slider post; there are plenty of sliders to adjust. However, don't expect a game as polished as 2K16; 2K24 has quite a few bugs and inconsistent features. When it comes to coaching and offline play, 2K16 may have been the best in the series in terms of quality and content.
