I think you hit the nail on the head, give me what I need to know when I need it, and make it more environmental when possible. Halo for example had the assault rifle show the ammo count on the gun itself and other games have as well, there are countless other ways to give information organically to the player.
This is a great answer and I learned a new word today! I’m okay with diegetic elements, as it feels organic and as long as it’s not distracting I’m okay with that! I forgot about mirrors edge, the minimal(ish) design of that game is great.
I suppose saying “no HUD” was a bit narrow, the spirit of my question was more about games that don’t have displays and elements pulling too much attention from the game itself. I appreciate the response!
I think it just implies that since it’s out on a platform that pretty much everyone has access to, global productivity will plummet due to everyone playing it and getting addicted
