When playing games, I usually turn off or minimize the HUD for immersion unless there's some in-universe reason for it to be there (i.e. the player is a robot or cyborg, or is wearing a visor that overlays information into their view). While often useful, they can also be distracting: an ideal system is to be able to toggle the HUD on or off as needed. Even so, some games don't give any option of resizing an intrusive HUD, forcing the player to mod it out of the game lest the screen become filled with shit.
