... had to update the link:

I'm updated the NPC generator based on the feedback, should have a new version posted soon!

Way too many missing limbs, seems like more than half were missing an arm or leg...

Cool, I'm glad it was useful! Good feedback too! I agree some of the details (like missing limbs) need to be less common, and I need to increase the number of unique details (cloths, weapons, quirks, etc.).

I've posted an updated NPC generator (same location as the previous version):

The update is based in part on the suggestions and comments made here, but some suggestions will require more work. I intend to make further improvements, so please keep the suggestions coming!

It should only be about what you "see".

The NPC generator is meant to be a tool for MCs. If the PCs walk into a bar and the MC needs to quickly populate it with 6 NPCs, the generator provides a starting point. As the MC you decide how much of the information the generator provides is true: if it says Winkle is a man, but you want Winkle to be a woman, you just change it on the fly and maybe make a note to remind yourself. Also, as the MC you decide when the PCs learn specific information: no reason you can't say Winkle looks like a woman even if you (as the MC) have decided Winkle is in fact a transvestite that may or may not be reveled later. This generator isn't intended to produce every bit of detail for every single NPC, just some basic info for the NPCs that fill the MC's world but who the MC hasn't already developed.

I'm relatively new to Apocalypse World and this forum, so maybe this has already been done, but I've written a random NPC generator for Apocalypse World:

Feel free to use it, make your own versions, post suggestions, and so forth!
