I'm aware in gaming terminology that HP = Hit Points.
But when I first came across HP and MP, I assumed they were Health and Magic Points. H standing for Health seemed logical and obvious, and I would have never considered Hit. Even now knowing it's Hit Points, when playing games and someone is low, Hit never enters my mind.
Say I'm playing FFXIV. I'll think 'someone needs more HP' or 'someone needs more health'. HP and health are interchangeable, so unless you factually know HP stands for hit points, it's easy to assume HP equals Health Points.
So yeah. Hit Points is correct. But I still think of it as Health Points. Hit just sounds weird amd cumbersome
If it makes a difference, I never ame across HP until I played FFVII
