Player should travel fast. He should bunny-hop, levitate, move to another surface. So that's why we insist on a high dynamic pace. It will be achieved with the help of our physics engine. Today gaming engines like Unreal or Unity provide us with the incredible level of detail from physics perspective. Take a drop of water levitating in zero-gravity, for example. It will interact with different objects. if a rocket flies through it, it will leave a track and it can stuck in liquid. And it will also affect player.
