Uh.. well.. This concept is meant as a tongue in cheek parody piece more than a real, honest to Chaptor long-term project. I'm not even sure if it'd be appropriate for here, /draw/, or /cog/ given the bizarre and asinine nature.

I'll spare the origin story and just drop it for what it is. However it happened, my brain crashed the idea of drawfaggotry and Mage: the Ascension together into one terrible abomination of pretentious fluff and game mechanics. The concept is that you're a drawfag. A banal creature from the back alley of imagination. A formless, sentient wisp of creativity and thought without any substance or presence until one day, poof, you're a manifest imaginary in a realm of limitless possibility. Your ability to touch, perceive and interact limited by your ability to draw. As a toon, you make your own reality and interact with others.

Why Mage: the Ascension? Because the system is one for dynamic effects on storytelling. In M:tA, your little character doesn't use mana, or consume traits, or anything like that to do their stuff. Comprehending the fundamental forces of reality (called Spheres) and the applications you seek to put them towards is the only limitation to how they can affect their environment.

..Then I realized that I'm not really an all that learned or practiced drawfag and couldn't hope to boil down all the minutia of art fundamentals into proper stats if money depended on it.

That's where you people come in. This isn't a serious project, it's just something to shoot the shit over and contemplate over lunch.

In this scenario, I liken the Spheres of the tabletop game to disciplines the artist has to keep in mind when working on a piece. In the tabletop game, there are nine of them.
Correspondence (space,) Entropy (probability,) Forces (fire/ice/lightning/sound?,) Life, Matter, Mind, Prime (power,) Spirit and Time.
You can do just about anything in the game with understanding of how these spheres work. Make or do just about anything. The idea for Drawfag: the Whatever is to come up with some things for drawfags as fundamental for artists as the Spheres would be for a mage. :)

From where I'm standing, I've only come up with a few ideas. "Lines", "perspective", "light (shading)", "special effects", "expedience (how fast you can draw any given thing)", "realism", "visualization" or what have you.

It is impossible to "minmax", because it's not a real game. You could give yourself as high a level in whatever stat as you wanted, and it wouldn't mean anything. Nor is it a popularity contest or a source of roleplay drama. I guess really it's just a silly bastard child of /tg/ and drawfaggotry you could kinda study from. As well as playful ribbing at White-Wolf games.
Just a thought.
