Well, I think Nerf got the idea about Vortex is that darts instantly fall to the ground when they impact a surface, while Vortex can ricochet off a wall if impacted at a certain degree. I think Nerf got the Idea for Rival from the design of golf balls which make them fly further and they developed different flywheels for Rival so the new ammunition has different flight characteristics.
