Relationship points

Many characters have a relationship level that represents how they feel about Simon. Unlike most harem games, there are no gifts or other ways to gain repeatable points with any characters. Relationships improve only by making choices during the story, finishing a quest or section to a certain standard, or taking a character's advice on resource use (ie the Investments). Characters usually make their opinions clear before decisions, but bonuses are given invisibly.

A relevant point to consider is that, even if the character is not on your harem yet, your investments or choices already change her relationship with you.

We've divided each character's points onto their individual pages so you can max them, but this page will gather some information about the mechanics in general: The exact scale isn't clear, but it seems that the range isn't between hatred to love. Most likely a 0 would mean an extremely reluctant ally, as even the lowest starting value doesn't represent hatred or an enemy. Characters above 25 seem to be loyal with a few reservations, while very loyal characters like Qum start out at 50 or higher. The highest starting relationship level seen so far is Robin, with 80. A relationship level of 100 represents complete acceptance and loyalty, and thus is marked by accepting Simon's decisions even if they disagree.
 * Maximum affection is 100, and once there a girl should not lose affection afterward.
 * Repeatable sex scenes are unlocked at different relationship levels. Most characters unlock a new scene at 50, 75, and 100 (but not all).
 * Character titles change with relationship points. Most characters have 4-5 titles.
 * Non-harem characters with relationship points are presumed to be future harem members, but this is speculation (although very likely).
 * Sierra has stated that it will be possible to max all characters, but it's not guaranteed. Based on the points so far, it seems very likely that some characters will be more difficult to max than others.

It's worth mentioning that this system doesn't seem to represent love or affection, exactly, but more how much the character trusts Simon and how well their goals align. Qum, for example, is fanatically in love with Simon from the beginning, while Megail doesn't turn all mushy even at higher levels. By contrast, Robin has a platonic father-daughter relationship with Simon but starts with the highest value. Given the game's character and political bent, this dynamic is unsurprising.
