I don’t have any experience in dating sim games, but are you able to check affinity as you go along?And don't all actual player-choice games start at zero? Which makes me wonder why didn't FF7 characters start at zero? I guess Tifa having prior affection points for Cloud makes sense if the gameplay and story were interconnected but the affection points ended up being kind of arbitrary and meaningless anyway?
Using the affection points in FF7 as an argument fundamentally seems odd to me because it’s such a hidden stat, there’s no way it was designed with the intention of players being aware of it. Certainly more utility minded answers to why it’s set up hold more weight?
