KOF13 is still one of the best fighting games ever made and the worst part is that everything about why the game's aesthetic succeeded can be perfectly replicated in 3D at this point. There are very few smush or smear frames at all with 90% of the work being tracing over 3D models in the first place but what makes it stand out over the 2.5D fighters is the snappiness and color grading, and there was also just really good sound design beyond the sprites to put it all together.
