I came across GUMSHOE when Esoterrorists first came out. I bought the book but, not being into that flavor of horror, I didn't get very far with it.
When I heard about Mutant City Blues, I bought the PDF as soon as I could: I am rather a big fan of the superhero genre. Shortly after, I added the two casebooks to my collection.
I'm looking to get a game going, but I have a hopefully not too difficult question.
Generally, when I go about creating a character, I start with a concept and see how I can make it fit into the system. As part of that, I try to figure out what I guess would be called benchmarks. What values represent the human average and what are the ranges of human capability? How strong is strong? How smart is smart?
I'm having a bit of difficulty discerning what numbers to use in GUMSHOE and MCB in specific. I understand that even a rating of 1 in an investigative ability denotes a professional level at the skill, but what about general abilities? For example, if my character is a black belt at a martial art, what value of Scuffling does that translate to?
Any assistance would be greatly appreciated.
