I really don’t like repeating work. As a result it was super easy for me to get distracted world building for a playtest of that system I made (it’s currently called Skill Monkey because the way I designed it, eventually long running characters will probably have a very long list of Skills).
I decided on “notShadowrun” as the setting ie using something similar but different to the dystopian cyberpunk Shadowrun universe but also casually doing a lot of our own thing.
