a tip i frequently find myself telling home GMs/MCs about tabletop games: do not design a setting with the same level of thoroughness as you see in an existing ttrpg book. we have to do that as ttrpg authors because we are trying to provide lots of interesting hooks for lots of different potential adventures at lots of different tables. you are hanging out with four or five other people. your setting only needs to interest y'all. don't make 60 factions when 6 will do
