Axel, I have a small request. Can you edit the formatting of the summary for this sub so it's not spaced so far at the top and bottom on the main page? It's nothing huge, it's just irking me in the same way that an image that stretches your screen horizontally does.
It is good that you brought the topic up, but generally, I found applying dice modifiers to love unnecessary - players who care about the characters and NPCs enough to be bothered by the concept of love will act it out - and sometimes deliberately fail rolls; likewise will they succeed without rolling against fear and the like when their loved ones are in danger; often these scenes will be entirely roleplay and no system.
So, good idea, but approach it from a different angle.
