I remember these when they came out and were getting passed around on flash sites. It was maybe a couple years later that they remade the animation- my brother and a couple of our friends were so excited we all gathered around a computer to watch it together and we were all floored!
I think the one you linked is, by far, the more recognized one.
Killer Instinct, arcade and SNES Killer Instinct 2 (arcade) which was kind of ported as Killer Instinct Gold (N64)
Those are my top tier without a doubt.
Bloody Roar : Primal Fury was absolutely excellent as well.
