It boggles my mind that anyone would think the rules are the physics of the game world.It boggles my mind that the inhabitants of a world would not be putting in at least some effort to understand their world. I mean they must know something right? bigger swords do more damage? Fireball has more killing power than firebolt? I can't make a potion of invisibility unless I can cast invisibility? Adventuring makes you better at what you do?
I mean, it’s fun to pretend they are when it leads to beautifully ludicrous things like the Peasant Railgun, but not for stuff that’ll see the light of day... err... play.
