What I think is lacking in most animations pack is variation. Most of the time, there is always only one real variation of an animation (sometimes, there are multiple animations for the same action, but they can hardly be count as a variation). So what I would like to see for example (especcially when it comes to gesture animations) are animations of the same action, but made for different type of characters/moods. (when I say character here, I mean personality).
I hope this is clear.
As for the assassins creed like climbing and parkour animations: I dont think this is any different from common walk/run locomotion animations… And I think it’s very easily integrated into the Advanced Locmotion System (i didn’t look inside yet, though I bought it).
