The health bar, or hit points, is more than just an indicator of physical damage. Its origins go back to Dungeons & Dragons, created in 1974 by Gary Gygax and Dave Arneson. It was a revolutionary concept that changed the world of gaming. In early editions of D&D, hit points (HP) were an abstraction. They included luck, morale, light scratches, and the ability to dodge. A character with 1 HP wasn't dying, but simply very tired or unlucky, but still combat-ready. This concept quickly migrated to video games. While Pac-Man (1980) had binary health, Wizardry (1981) and Ultima (1981) had already implemented numerical health points. This direct borrowing from tabletop D&D role-playing games became the standard. Therefore, "loss of health" in D&D and many RPGs doesn't always mean a bleeding wound. It could be a loss of balance, mental exhaustion, or simply a failed block. Characters with high HP could withstand blows without sustaining serious injury. Thus, hit points are a complex measure of endurance and luck, not just physical damage. This D&D innovation still shapes the design of thousands of games, from Final Fantasy VII to Cyberpunk 2077. What do these points mean to you?
