With Love/Hate, your characters will…

…have personalities and emotional states.

Love/Hate uses powerful, customizable personality and emotional state models.

…maintain relationships.

Love/Hate tracks how different characters and groups (factions) feel about each other, allowing you to define a dynamic web of social ties among your characters.

…judge and remember deeds.

Characters witness deeds committed by others, judge them according to their own personality and relationships, and remember them.

…and gossip with other characters.

Characters share memories realistically, allowing news of actions to spread organically.

Love/Hate lets you create complex characters that react emotionally to what’s actually happening in the game. No scripting required.
