Victoria Rules
There can be to a small extent, as abstracted by making a lot of the physical side of the character creation process random: random species, random gender, random stats, random height and weight relative to species averages, random age (within a playable range), random family elements, etc. All of this reflects the idea that you can't choose what you're born as or what family you're born into.It's not a matter of not being able to get an exact match. It's a matter of the choice--what the character is biologically and what skills they practice--being one that is not and cannot ever be diegetic. Nobody gets to be a disembodied spirit with an encyclopedic manual of possible persons they could elect to be. We are thrust into this life without our consent and forewarning.
There simply is not any mapping between character creation and real life. There can't be.
Previous professions, current class, etc. are things the character has had much more control over during its life up to now and thus having those chooseable by the player makes sense.
By giving DMs the freedom to overrule what's in the books, isn't rule 0 supposed to take care of this?The books (for 5.0) straight-up explicitly say that humans/elves/etc. are present in effectively all settings, meaning they are instructing DMs they aren't allowed to not use those tools. That's not something a "toolbox" should ever do--period.
