One of my released 24hr games has no need of any monsters, critters, etc... only the humans... and char gen is fast enough to use for NPCs. The question to answer for the PCs... "Who am I?" ... on an STL interstellar colonial ship.Maybe it took you a week, cobbling together bits and pieces of systems you like. Maybe it took you months or years, but eventually you say "at last, rules for everything!".
Then you realize in horror that you need to create enemies. NPC's. Monsters. And somehow figure out how to make enough of them that feel different and interesting, as well as determine what, exactly, is a balanced encounter..
