I currently have part of a game rolling around in my head, and one of its operating principles is matched pairs. That is, pairs of stats that are either opposed or must have resources divided between them - more in one at the expense of the other. Although this has worked flawlessly for part of the design (ship combat), I haven't yet extrapolated it to characters. I'd like to. (And before someone suggests it, I'm aware that Pendragon's Passions work on this principle, but I can't lay hands on a copy in short order.)
So, for character "stats," what would make for good matched pairs? For example, I see Reason vs. Intuition (or Logic vs. Emotion) as a good one. Basically, I'm looking for matched pairs of tools a character might use to solve problems and negotiate conflicts. I don't currently have any bias about the nature of resolution, so physical, mental, psychological, social, and educational stats are all fair game. What I'd really appreciate is just people's ideas to get me jumpstarted.
Thanks in advance,
