I'm sure I've seen this mechanic about twenty years ago somewhere.
> Link and the objects he rides on move together at the same speed, rather than Link being technically stationary on top of a moving object as is common in the physics of other games.
This is just how physics work. Aside from the absurdity of trying to patent "simulating basic physics" , I'm sure simulations for this have been written countless times in the past decades.
The sad thing about this is that stupid patents are often accepted just fine, and Nintendo can later try and enforce them against some little studio that can't afford the lawyers to defend itself.
