That’s why good games give you the option to remove helmets during cutscenes, or just hide them altogether.
No. I want to see my cool helmet. Games that remove helmets and (all customization) during cutscenes annoy me.
ideally i’d want games to have NPCs react to if you’re wearing a helmet or not, and a real risk of getting attacked when in populated areas, so you have a choice to make whether you want to keep your helmet on or take it off (and that should be a simple button press)
that way there’s a bit of added flavour, and you have an actual reason to see your character without a helmet.
