Which Dragon magazine issue is this in? How does it work?
#346.
Essentially, you get out your three dragon ante cards, or take a deck of normal cards and modify them slightly. You then take a number of tokens or pennies, depending on the point buy level you are using from the 3.5E DMG (We use the 3.5E method to determine abilities, and then port over to pathfinder, so we can use this article). I believe our group uses 28 points.
Anyways, you do a tarot-style spread for your abilities, and put the tokens in varying amounts on each card - there are five in the middle, and six on the outside, with each of hte outside six starting corresponding to an ability score.
The inner cards generally divide the tokens up into varying aspects of the charcter, depending on which card you drew (the magazine article explains this a bit better) and then the outer cards either steal tokens from other ability scores, or give their tokens to other abilities. In the end, you count the tokens on each ability, and figure out what point cost those abilities are at. And you're good to go.
We use an "organic" system, so players are allowed to switch one set of abilities to better fit their character. Generally, everyone has at least one stat of 15, and it's not uncommong to have a 16, though 17s and 18s are rare (I think we've only seen two so far). You tend to see odd character choices, and sometimes PCs have to make do with low abilities that they would otherwise not have - our inquisitor has an 8 strength, and one of the psions had to fight to counter his constitution of 8.
I like the system, because it lets us have random ability scores, without having the huge imbalance between characters caused by random ability scores - everyone's ability scores tally up to the same point total, after all.
