David Blandy, designer of ECO MOFOS:
"[I]f I was going to give a formula for creating strong NPCs with economical writing , I think I’d combine several of these approaches and write something like this:
Name, rough age, notable physical detail. Skill, Skill, Skill. One Obsession. One Secret. One Burden.
So:
Dillanger, late 40’s, thick pink glasses. Laughing, smoking, deducing. Needs New Things. Is ashamed of their past cowardice. Weary.
I can imagine Dillanger running a weird curios shop, getting friendly with the Players, and trying to pursuade them to gather new stock. They can’t get it themselves as they don’t trust themselves to follow through going to dangerous places. This constant tension between wanting new things to look at and being unable to procure things directly makes them Weary."
