Get 1d100 character relationship ideas here.
I started using the above table of 1d100 character relationships to start campaigns.
I wanted to get over the initial awkwardness of, “Why would these characters work together?,” that I have seen before. I also frequently have players who don’t know each other as well, and using the below table creates something that two players can quickly share between there characters to get the RPG gears turning.
I normally try to make sure each character has at least one relationship to another character.
A rolled result might not fit with someone’s planned character concept. I normally try to encourage a loose interpretation of a rolled result, or tell folks they have broad lee-way to interpret the rolled result. But if all else fails, then they could fudge and re-roll. If you’re worried it won’t fit your group, check with them first and get buy in. But as with all things, YMMV.
