Traditional animation is the expansion of the timeline-driven storyline.
Advantage does not seem to have,
The downside is that many duplicates require human control and are awkward.
I have found that many times animations need to be driven by events to drive changes in logic and objects.
Their results can be random or absolute.
This is very similar to the game. A lot of less important things are automatically triggered by events to get good results.
It has the advantage of being able to handle the interaction of many characters and scenes flexibly and automatically.
Very convenient and flexible compared to manually setting keyframes.
So I think that Blender can consider the concept of event-driven as part of the animation function even if the game module is removed.
With the advent of interactive video, I think this may be the future trend. There will always be boundaries between games and animations, but there will be overlaps between them.
Maybe the animation of the future is real-time rendering, which can interact with the audience in real time.
