We take for granted now how much especially the defaults for Halo 1 rebuilt gamepad controls to a useful, reusable standard. It's really fun going back to Halo 1 and its tutorial of how its controls work and its menu full of optional entire layouts to sort of see the exact moment when game controls stopped being lousy and almost random from game to game. You can contrast with Halo Reach where most of the optional layouts are just gone and more people use the defaults and then say Halo Infinite where all the optional layouts are gone because the common ones moved into the platforms (and accessibility settings) and in some cases the gamepads themselves.

It remains an interesting reflection point in the history of 3D games. It's also why the Grim Fandango remaster turned out so well, now that controls have settled into their modern forms.
