I generally don’t think much about lifepaths when I build NPCs. Of course, the small NPCs that come into the story all the time, the ones I never make full stats for, those I just assign whatever relevant stats they need off-the-cuff. A thug has a 3 or 4 brawling, but usually is untrained in Perception. The opposite for a merchant.
But what about the big ones, the important story-centric NPCs? Especially the nemesis types? I see in little references here and there that Luke burns them up with Lifepaths.
Do you usually burn up important NPCs with lifepaths? If so, do you add a few points here and there when you’re done, or leave them like starting PCs?
