ELI5: Why is it so hard to make walking up or down stairs in video games look natural?
gpt
For one it has to do with the fact that most video game characters don't move at a normal/natural pace. Because of this the game models transition from a run/walk to walking/running up stairs will look weird unless you have the game character go up the stairs two or three steps at a time. And even then you'll have problems.

Simply put... The pace at which most people go up stairs, and which looks normal/natural to us, isn't conducive to a stimulating gameplay environment.
