I forgot the Josy sec scene, good call. As for Sage and her Rp, it's a few points at most. Given the req's for the others, I really can't see it making any differnce personally. As a side-niote, this will annoy the dik lovers, but have you noticed a pattern yet? Bella does prefer a chick, Jill's content is behind Chick affinity, Maya&Josy are chick/Neutral....all of Sages content be got by cchick also....
Maya and Josy content is really weird and contradictory. The Ep 1 Josy scene has extra scenes for DIK chars, not chick. The ep 3 Maya scene is different for MASSIVE DIK -or- MASSIVE CHICK vs any other status, or you get everything based on the RP threshold.
As a whole, it makes a lot of sense that early interactions and impressions and willingness to do stuff, or stuff with people who don't know MC well, is governed primarily by DIK/CHICK status, and that long-term interactions are governed by RP. But then you have Maya in particular oscillating around between all of them. I guess you could say that's due to her emotional turmoil or something, but it's probably just due to DPC trying different stuff out. Overall it seems like in Season 1, Maya/Josy were intended to reward 'neutral' affinity characters (with Isabella/Jill for Chick and Sage/all the casual sex encounters for DIK), but in Episode 5, Maya and Josy are definitely also in the chick column.
I think with a system like RP, it makes sense to use it more later in the game to reward consistent behavior. The early thresholds have mostly been easy to reach (Ch 3 Maya probably the most difficult? and still not hard), but the things they've changed have also been pretty minor - tweaks to sex scenes, a kiss, etc. If the decisions/options using RP are more pivotal down the road (and you'd think that's the reason of tracking how much various people like the MC), you would probably expect the thresholds to rise.
Honestly I think this is pretty good as a development plan. I recently played City of Broken Dreamers, which is really excellent! But one thing that really stood out to me is that there are so few opportunities to interact with many characters that achieving certain thresholds ends up coming down to one very specific decision or another. In Being a DIK, those kinds of options are usually governed by DIK/CHICK status, which you get a lot of opportunities to modify. Waiting for RP to accumulate to significant levels before utilizing it in a significant way makes sense, because it prevents situations from boiling down to "Did you choose option A or option B 4 chapters ago? If you chose yes, you can see scene X. If you did not, nope." Stuff makes more sense in storytelling and is more rewarding when it's a reward for consistency - CHICK/DIK works because you're constantly given the option to influence the score, and then you constantly get feedback based on what the score does for you. It works a lot better than individual-character affinity system until you have a LOT of history with a given character, when it starts to make more sense for that character to judge the protagonist based on their personal history rather than your recent public behaviors.
Just for example, imagine if there's some kind of scene where MC is trying to tell Sage what's going on with Quinn. It would make a lot more sense for how much Sage personally likes and trusts MC (her RP) to govern whether she chooses to trust him than his DIK/CHICK status. It's not hard to imagine hypotheticals for the others of similar impact where having RP be the governing factor simply makes more sense. There have not, thusfar, been very many situations where that is appropriate. As characters know each other longer, RP makes more and more sense as a game mechanic. You can also particularly imagine situations that use RP but where the RP threshold differs depending on DIK or CHICK status. A DIK character might need a higher proportion of available RP to convince Jil than a CHICK one, whether that be from reputation or a reflection of the way that MC's dialogue is different based on their DIK/CHICK score.
