As the d00 system has evolved over the years, one question we seem to get a lot in emails and at conventions is "why isn't there an Athlete skill?" The truth is, we had one in Covert Ops during development. We removed it intentionally, and so I thought I'd take a moment to explain and hope that some folks comment and help convince me otherwise.
One thing I like to ask back: how do you define athletics?
If you define it by describing flips and tumbles and leaps and rolls and running and jumping and more, then I always suggest that perhaps your character should have a good DEX score and a descriptor that you "like to perform feats of acrobatics" or "engages in parkour" or even something more fun like "hoppy-skippy-jumpy." Then you'd have high chance of succeeding in such activities, and earn some extra DP for doing it. Win-win.
Athletic training is indeed a real thing. Making your body stronger and faster and more coordinated is the goal of most athletes. But the goal isn't to make someone good at football or track & field; the goal is to make someone have more effective core attributes which result in being better at football, gymnastics, etc.
And that's where we draw the distinction.
The very act of making yourself a better athlete makes you better at all other uses of those physical attributes as well. Therefore, it's our opinion that you make yourself a better athlete by working on your strength, stamina, maneuverability, balance, grace, and coordination... or whatever physical ability scores represent a character in any given incarnation of a d00system game, not the other way around.
Okay - so that's our rationale. Poke holes in it and convince me I need an Athletics skill...
