Better late than never (my link, I mean, not her post), I give you Mo’s Relationship Web Builder:
So I thunk this tool up a while back, and am looking to develop it further. It combines the Blood, Violence, Sex, Money ties that Brand tells me are from Sorcerer Soul into a process not unlike Dogs Town creation. I tested it out on Dave Cleaver, and he came up with something kinda nifty. For now it can be used to create a web in any game that has no explicit tools to build such a thing. Maybe at some point Iâ€™ll actually build it in to one of my games.
You can get some really interesting relationship maps by following the steps she lays out, and be sure to read the comments for even more ideas (and maybe offer some of your own).
And you should probably read the rest of her posts while you’re there.
