How do you add new NPCs?

Are the NPCs in the game completely randomised, or is there a way of making a specific personality with a specific image? I think it would be pretty cool to be able to add all my real life mates into it, somehow. Looking through the text files, it looks like it’s randomised though. Is this something that could possibly be patched in or looked at?

hmmm thats an interesting idea. Its randomised at the moment, with the names read in from the csv files (random mix of first and last names). But I like the idea of having a separate file of fixed people. I may well have to add that.
