Quickly flying through some posts in this topic I can't help but notice that some of romance's opposers only consider it to be some sexual side dish when properly done it would (or at least in my mind should) be about love but not in its Hollywoodesque form of flowers, chocolate and sex but ever-growing companionship, caring and deep emotions. Being a pledger I naturally have no idea what the story-setting is but I'm gonna take a wild guess that end of the world is somehow related to it so strengthening your relationships with those close to you in a form or another would be reasonable to expect.
After all, don't we all want as immersive game world as possible?
PS. Someone with more talent in English could explain my point better. Rather hard to make a speech appealing to emotions with non-native language :D
