I am compelled to write more on yesterday's subject.
I find myself quite contentious on the matter of people who want to limit the game on the basis of what players are willing to play or what players are comfortable with. This only means that the solution MUST be more creative and far-reaching than the limited imaginations of those who dismiss the idea of out hand.
At the risk of repeating the very, very obvious, SEX and LOVE are central, immutable elements of the human soul, more so than morality, magic or social comfort. The failing here is not that these are not subjects suited for the game ... it is that the game at this time has not risen to the importance of these subjects.
Oh, you may sit upon your toadstool and preach the comfort zones of your players, but were someone to offer your players a rational, reasonable and playable option for them to get HIGH on their characters in love, they would grab it.
So far, I've seen people speak of all the negative aspects. Of course no player character wants to settle down into a marriage. Of course no player wants to be gay or have to suck up to a loved one's possible disapproval. And no DM wants to get into all the bullshit of when a player's lovelife makes a social modifier and when it doesn't.
Playability demands that the whole situation MUST be viewed in terms of how it can be measured mathematically. We're perfectly comfortable measuring intelligence mathematically, or wisdom, or your beauty. We have no trouble with numbers for how likely your men are to obey you! All existing social aspects of the game are already measured!
To remotely consider roleplaying as a fundamental solution to the matter is to propose NO solution, or to propose that a solution ought not to be supposed. It is Victorian thinking, my dear gentle readers, and its as ignorant as Aleister Crowley and his midnight dinner parties. You've thrown in the towel before you've begun and damn your frigid, turgid genitalia to your mother's narrow womb for that bullshit.
Betwixt the fantasy and the playability of D&D, my dear readers, a lover is a prize ... it is a phenomenal thing that is to be obtained, just as one obtains gold and magic. it is, indeed, a 'magic' item ... one that must transform your character's kicking ass ability just as it does Parzival and just as a +4 Dwarven Hammer would. The only thing that needs deciding isn't WHAT love would do, but how to obtain that kind of love. We do not speak of the bar wench, or the piece of tail selling itself on the street of silversmith dildo-makers. One does not wrench free the broken end of a smashed stairwell's bannister and call it a magic weapon. Just so, one does not slap wet skin with the farmer's daughter and call it Guinevere.
So please spare me the conditional expectations of your players. I do not care a whit for any such persons more pre-pubescent than their teenage children. As ever, I'm looking to break the expectations here and lift the game out of its perpetual self-inflicted infancy. Help or do not, but don't tell me its impractical.
