Are there any games that keep track of relationships between PCs and NPCs? Fallout has a reputation system where you get bonuses or penalties to settlements depending on PC behavior. Delta Green has Bonds which are people or institutions that help keep you sane. Lose of Bonds can make it more difficult for PCs to recover from sanity blasting creatures.
As noted, many PBTAs bake this in; from Apocalypse World’s “Hx” which is both positive and negative to represent how you view other characters forward.
The “old school D&D” flavored Freebooters on the Frontier HAD bonds, which tracked this with PCs and NPCs alike to reflect relationships and played into some of the moves around teamwork & relaxing, but just changed it to Trust which I think reads pretty cool. A couple other games I’ve seen track that, which can be very interesting when not reciprocated!
