I saw this one interest check a while back. I don't remember whose. But it was for a cop 1x1, and the characters were going to be partners, two male detectives. I recall the player stating that there would be no romance. They just wanted some partner bonding and some butt-kicking and that kind of thing... which is totally cool, don't get me wrong. But me personally... I see something like that, and I'm bored before I read the rest of it. I don't see the plot idea so much as this Big Wall that has already been erected (hyuk hyuk) between the characters before the game has even begun. Like... I don't want a 1x1 game like that, because I'm limited with where I can take the characters.
But... you know, take the same idea and change it up, and suddenly I'm more interested. Maybe it's an older veteran cop who's a chauvinistic pig and he gets stuck with the bright-eyed Girl Power female cop fresh from the academy. Or outside of my comfort zone... maybe it's still two guy cops, but one of them is gay, and they have to deal with unrequited feelings and whatnot. Or two girl cops with the same thing. Or... whatever. I'm just saying, having that option of some kind of sexual tension gives the story much more potential, in my opinion. That Big Wall prohibiting such things is not there. And the sexual tension doesn't even have to lead to anything for it to be intriguing, honestly. It just allows you to add some extra flavor and drama to all the things that could possibly be played out with the original plot up there.
But anyway, that's why I asked. I tried to think of some 1x1 plots I would enjoy that prohibited romance and whatnot, but in every case, I decided I would like the same plot even more if it did not prohibit such things. I thought perhaps since you had the grievance with romance in 1x1, you had some alternative ideas I had not thought of.
Just some thoughts to think upon.
