For a time there were only a few controller schemes the game world was used to:
3D environments:
First-Person Shooter(FPS): Keyboard and Mouse
**Third-Person: Controller (Grand Theft Auto(GTA)) scheme**
Driving: Was X for gas on the Playstation and A on the Xbox
But trigger sensitivity and more buttons helped the evolution of the controller inch it’s way closer to the keyboard and mouse. Once the combination of buttons is established, some characters migrated to controllers only while many remained in the keyboard and mouse space.
Because of the evolution of control schemes and camera options, 3rd person gameplay has become a standard in its own right. Grand Theft Auto is, arguably, one of the games that made 3rd person control schemes a standard, leaving FPS schemes to their own genre. There are exceptions based on camera settings such as Resident Evil 4 and Dead Space.
