Something I’d like to note that walking becomes very diffrent for males and females. As knowing someone who has done a lot of medieval reenactment groups the women often tried to walk and move as men because it was mostly men on the battlefields. It was very interesting to hear that the why the female members realized how to walk as men walk, was to practice waking as if their was a book between their legs as.... you know, men have to deal with dangling bits while they walk.
Same for a lot of my male cross dressing friends. To walk like a women they have to make the same changes in their steps to account for the fact that women don’t have to deal with dangling bits.
Even with the physical diffrence, they can still posture and pretend if they try hard enough, but the fact is without trying it’s much more natural for women to easily walk with a sway as men usually walk with their legs parted.
As for “is it nessasaary to have two distinct gestures for men and women in your game” I REALLY feel like it just depends on the type of game your playing, if it’s a sprite game like Pokémon I wouldn’t see the reason for the extra step. If your making a game like the sims where everything is super customizable, then I’d expect lots of Intresting gestures.
Altho I do admit I hate it when the gestures made for men and women are very.... basic. Like in dragon age 2 I noticed that the females had a much more Danity feel to them then the males. Which was fine when playing a Danity mage.... but not when I wanna play a bulky amazon warrior, just clashes with my vision of my character x3
