Ironically, Nintendo invented actually pretty groundbreaking stuff in the past, but apparently without patents, such as making the player character steerable while in the air (Super Mario Bros) or making 3D third person controls relative to the camera instead of relative to the player character (Super Mario 64). Basically every 2D platformer and 3D third person game uses these techniques ever since. Of course they also copied a lot of mechanics from other games themselves.
