I had this idea a couple of days ago while reading this post on B/X Blackrazor. Rather than rolling up ability scores (strength, intelligence, wisdom, constitution, dexterity, charisma) you would roll up certain traits or characteristics for your characters. I'm working on a list of 100 traits, I have about 60 so far and am slowly cranking them out.
Essentially, instead of having a high strength giving a character +1 to melee attack and damage, I might have a character that has a "Bulky Build" or a character that "Sleeps with his Eyes Open." Characters also include races, such as "Dwarf", "Goblin," and "half dragon centipede" or professions, such as "farmer", "blacksmith," or "astronaut."
A character with a Bulky Build, for example, gains a +1 bonus to damage, but must have armor resized for him (costing twice as much). A Dwarf, on the other hand, has a 2 in 6 chance to notice inconstancies in stone.
At the beginning of the game, a player would roll up a trait for his character. While traits aren't exactly balanced, there wont be any character with three 18s and anthers with all scores below 6.
When I finish up the chart, I'll post it here and say a it more. To speed things along, it would be pretty cool if you guys could post a couple characteristic ideas as comments.
By the way, I'm still looking for a few more players for my PBP Carcosa game. Just tell me if you're interested and I can reserve a spot from you. I'm planning on beginning character creation as soon as Finarvyn get's back from his surgery.
