Quick and random thing to share (or at least, make available to myself for when I'm curious about it again later on)
Regarding hit points, specifically in 4e D&D:
Of course they talk about how hit points are abstracted, and healing is sortof abstracted too, but then they mention it in a way that I hadn't considered it before.. Getting "hit" and taking "damage" reduces your hit points, but for narrative purposes, perhaps you're not really getting injured and at risk of dying until you're just a whack or two away? All of those other hit points are just a measure of how the fight is going for you.
Dunno, it caught my eye :)
