Books, films, and games to some extent are mostly vicarious entertainment to me. They allow me to experience something I otherwise could NOT.
That's the main reason why I am not overly partial to romances in my content. It seems redundant in a way. (At the same time I see how others are fond of them of course.)
Though even so I like to write romantic stories in my pastime and I have made a point of the emotional factor and the developing relationship to be a focal point of the narrative rather than plain cliffnotes, and give them months or even years to spark, flower and blossom before thriving - or withering and dying. Love on first sight is quite implausible in my experience, at least when you look at how long it takes for those relationships to break up again; and gets real old real fast. (Congrats to those who did manage to make it work, of course.)
Yet how many games, be they deep story-driven RPGs or casual action flicks, take place over the course of several years (ingame time of course)? Most of those romances I see are developed over the course of less than three dates.. and you know what is being said if you give in before the third one. And then you get a meaningless one-night-stand. Well done to me would mean that they have some relevance to the overall story arc. Though what most here want seems to be as aptly described just that - a minigame.
Inter-human relationships deserve better than that. At least in a 'perfect' world. Some even suggested to have them entirely detached from the actual plot as in Mass Effect when the story (what little there was) would constantly grind to a halt so you can muck around with your potential love interests on the ship. Or not. It's your choice! (But no consequences.)
And after everything is over? No further mention. Doesn't that help to make them seem even more vapid and empty. Especially if you switch partners in the sequels without anyone even caring to comment on that.
An anti-example might be Vampire - The Masquerade REDEMPTION. Yeah, nobody remembers that one, do they? It wasn't great, it could have done a lot better, but at the core of it, it is a story about love that seems doomed from the start, yet endures hardships, countless centuries, and in effect even death itself. Every action is motivated by it.
So if you're having these kinds of events/activities, make them.. hard to get.. realistic. Why not even platonic, for a change? Meaningful. Lasting. Until you aren't ready to put up with that.. you.. well.. I don't know.
But even that was probably brought forth in previous ramblings that I can't read due to my ADD, so how about closure if we just all agree that Christopher Walken is awesome?
