When making a character in the Pathfinder setting, most of a player’s resources go into the class, feats, and skills of their character. The system is geared towards the backstory being an afterthought. How many players gave their character a name and background last? This is what pulls people toward games such as FATE, White Wolf (now Onyx Path) games, and others. I believe there is a way to make social interaction which includes the character’s background boons, birthrights, allies, and contacts more integrated into the d20 system.
On character creation, players will be given a certain amount of points to use to purchase Social Advantages. They are similar in nature to feats but the strict mechanical advantage is not always immediately apparent. Advantages are only purchased at character creation (This may be changed later, other ways to gain advantages might be by arc completion or give them points at certain times to purchase a greater version of a current one). In most campaigns where the players’ social interactions are not the focus of the campaign are given 10 Points. In a campaign that has more intrigue and is centered on dialogues, plots, and intrigue are given 15 points. This helps interweave the players into the plot and make them insiders to the plot instead of mere observers or outsiders.
