oh yeah i agree with captainmeme
can imagine your representations of gamestates right now as an N-by-1 matrix where for each of N players you measure
your
relationship with them while you could instead have an N-by-N matrix where you measure each person's relationship with each other person's relationship. The diagonal of this matrix can just be greyed out (or set to maximum affinity...)
it'll be harder to see all your notes in one place since they'll likely be truncated from cell to cell, but if you make the table right you'll be able to "focus" on particular players and see all your notes about them listed in full together
there might be some cool mathy things you can do with matrices like these to maybe predict relationships between people or other dynamics, but i'm not sure if such things would fit the context of an LSG game or not; interesting to ponder sometime maybe
