Hmm. I'd be partial to a romantic subplot, but - depending on the probable time span of the game - I'd like a more subtle, hinted romance a la Annah and Fall From Grace, since its lack of outright Shakeapearian declarations of Eternal Love, etc, allowed for a more open interpretation of both the end and the relations between characters. If it could be integrated seamlessly into the general characterization/banter of the character, it'd be great. In short, full characters, with a hint of something more, if persued through dialogue. Make my imagination fill the gaps with whatever meaning I'd like. Eh. I'm rambling.
