After 30 years, the game naturally reaches a point of diminishing returns. Massive gameplay upgrades simply aren’t realistic year to year.
Glitches, AI, etc should always be improved upon of course. But beyond the core gameplay, the things that can make a large visual impact year over year are animations/no-cap, presentation, play by play dialogue, and overall atmosphere. There will never be a shortage of real life elements to bring into the virtual game world.
I feel like the gameplay is solid. With proper sliders, it can play great. The shortcomings in this game are the presentation and broadcast elements, the small details that 2K gave us a decade ago. There is a lot more room to make up ground in these areas than gameplay (in my opinion).
With these yearly releases, often with the removal of features and very little added, these games should not be $70 launch titles. All sports gaming should be patched improvements over a calendar year rather than yearly titles.
I believe EA has addressed this and said the NHL wants a yearly release and wouldn’t accept rolling updates.
long story short - in my opinion - the game is far more severely lacking in the visual presentation and little details than the core gameplay.
