Nice one.
I actually recently got the game Arcanum, and while I've pretty much not played it yet, they do an interesting thing with stats. There are eight stats in all, and they're grouped into the physical stats and the mental stats. Each group had a "power", "resistance", "skill" and "attractiveness" stat. I can't remember it very well, but it was something like Strength (power), Constitution (resistance), Dexterity (skill) and Beauty (attractiveness) for physical, and Intelligence (power), Willpower (resistance), Perception (skill) and Charisma (attractiveness). I thought that was a pretty cool breakdown.
