Numbers?!?
Please!!!
(It has been already done to humans... in Europe, during the last World War... ) Oh my! I'm so sorry!! I didn't even think how it sounded! I was meaning something like what Lukerie says here:
you can name them a name and number their last names and when two people have kids, you put the numbers together, for example, villager 2 + villager 5= villager 25
It is an easy way to remember who their parents are.
I should have given an example.
You can be sure, I
always treat my villagers with the utmost respect and Guiding Hand kindness!
However, I don't want to cause any trouble, so I'll drop the idea. And I deeply apologize to anyone offended.
