I have heard of many games speak of game balance, and have often struggled with many of the ideas presented as such.
Game balance is, to me, all of the characters having equal opportunities to get the spotlight.
In games where failure is unfun, primarily those that have combat-to-the-death as common stakes for overcoming challenges, part of game balance is making all character feel like they can contribute equally and that the challenges are ones that they can overcome. In games without the forced storytelling of avoiding downbeats, it's just that everyone gets their moments.
My easiest example is a reference to DnD 2nd edition Dragons. I always wondered, how do you rationalize a scaley walking fire breathing barn, having the same HP as a 12th Lvl fighter?
This has zero to do with game balance.
Also, HP in D&D is at best only loosely correlated to do with how well you physically can handle wounds. If you look at 5e, a hit that does HP
literally is not hitting or hurting the PC until they are under half. (2014 PHB pg 196L Hit Points and 197

escribing Damage). This is important because D&D isn't trying to simulate reality, it's emulating the tropes and archetypes of it's genre, and the 5e rules (for example) are emulating the Heroic Fantasy genre. Where it's perfectly on-brand for a heroic warrior to be very hard to kill. It's not because they can take the same amount of physical damage, it's that they have the other qualities that make up HPs.
The dragon isn't as weak as a human. The dragon is mighty! It's the hero that has heroic traits of grit and luck and favor that elevates them.
At they time they were adamant about , oh its all about the minions, and the magic spell repertoire...etc. etc. But it never really sat well with me. In my own game dragons have hundreds and often thousands of HP, and hit multiple targets at once, and have multipliers on dmg. Suffice to say there have been very few dragon slayers in my world lol. I tried to base my rule system on what made sense rather than DnD's approach. What are your talking points for or against game balance of this nature?
This is great -- either you're aiming for a different genre which is a good thing to do, or you are positioning dragons as not a combat challenge. Either of those are perfectly valid choices.
