Well, one that immediately pops into mind is Cuphead, with its Disney/Betty Boop style.
One that I'm looking forward to (only demo so far) is Forgotlings, with its Studio Gibli inspiration.
One from the past that impressed me back in 80s was Prince of Persia, with its use of rotoscopy based animation (Karateka was first few years before it, by the same developer), sort of a precursor to mocap of 3D era.
One that will dominate in the future of 3D games is AI trained motion (I've been watching some Two Minute Papers on it in last year or so, it's astounding).
