Biological creatures are certainly not the only intelligent beings in the universe. Some settings may even be defined by the conflict between synthetic and biological intelligences. Others see androids and robots as a mere support cast, working as servants who only sometimes rise above their slave-like station to save the day.
The following systems are designed to allow for solid, functional rules for technological characters, while still allowing for the kinds of versatility you might find in programmable beings. In general, technological creatures are defined by the specificity with which they are designed. They are expert systems, less evolved for adaptability than organic beings but better at doing what they’ve been made to do.
They are automated and efficient, but their stories should involve them overcoming innate programming or design and becoming something more than just a person-shaped tool.
