I no longer need to come up with my own RPG campaign ideas. E.g.:
“The PCs are futuristic ninjas in a large corporation who, with their bare hands, fight corporate wrongdoers for gold in the Renaissance.” Sure, I can run that. The ninjas don’t get to bring their technology back and… the time machine went bad, so the plot arc is them trying to save money to bootstrap technology so they can rebuild.
“The PCs are mystic lawyers in New England who, with captured animals, fight aliens for purposes of fulfilling prophecy in the near future.” Yes. Yes they are.
