which game has the most elegant movement system (as a better alternative)?

First Hollow Knight is already better in that aspect, even though animation is less smooth IIRC. Personally, I prefer the Ori-Games in terms of movements, especially the second game.

But gaming is big, and inside as also outside the genre there are many games with great movement and controls. It depends on how much of an alternative you really want, just the movement, or the whole game..

I'm partial to super smash brothers melee. I feel like no other game has come close in making me feel so in control of my character.

That being said, it is kind of difficult to get into. Finding a good GC controller can be hard, and playing online is rough because everyone is so good these days.
