IP is a joke. Fuck copyright. Fuck patents. Nintendo is out here patenting physics.
"The movement of movable dynamic objects placed in the virtual space is controlled by physics calculations, and the movement of the player’s character is controlled by user input. When the player’s character and a dynamic object come in contact in the downward direction relative to the character (in other words, when the character is on top of an object), the movement of the dynamic object is added to the movement of the player’s character.”
These aren't even inventions. They are just obvious models of the real world that would occur to anyone who is trying to replicate physical interactions in a virtual world. https://en.wikipedia.org/wiki/Classical_mechanics
These are Japanese patents but I also have no fucking doubt a lot of this stuff has very obvious prior art even in gaming, to say nothing of other physics-based software packages.
Imagine an industry where this is normal. Naughty Dog registers a bunch of patents on the heavily cinematic nature of TLOU, and the chilling effect causes the producers of God of War (2018) to produce a completely different game, much more in line with franchise earlier installments. Mega Crit registers a bunch of patents on the unique combination of deckbuilder and roguelike used in Slay the Spire, so Daniel Mullins makes "Inscryption" with no path map, relics or cards, just to be on the safe side. In Horizon Forbidden West, the two times where you get to pick if you're Empathetic Aloy, Rational Aloy or Angry Aloy are removed because hey, don't want to end up going to court with Bioware...
