The only game that has those elements I've played is Harvest Moon (GameCube version). You have a choice of 3 girls that you can marry, you can choose one, convince them - otherwise the game will just give you a random girl.
Those cutesy games like Harvest Moon, and Animal Crossing - well they can be pretty dark sometimes. Anyway theres this one girl, little redhead, probably the coolest female character, free spirit hobo girl with a killer rack. Anyway I planned to marry her, but could never convince her, got really annoying. I'd go and speak to her, offer her a fish, or whatever - and she'd come out with stuff like ''Don't be so keen, just to say hello''... Like damn, this girl thinks I'm a loser! WTF!
Ended up marrying the farmers daughter, she's ok, but it feels like I settled for her. How depressing is that, when a game can resemble life so acutely... I was kinda in a relationship with someone I detested, we had a kid, and better options were coming out of the woodwork - my life was basically mirrored in Harvest Moon.
In Skyrim, I married Leia - again, one of the coolest female characters, and marrying seemed to just make her pointless. Now she sells the stuff I give her, she gives me money, she'll make me a pie if I ask her... but I do miss the days when we'd go out, owning bandits and generally kicking arse, how we'd laugh when she caught me checking her side boob. Those days are gone - taking her on a quest would feel like a chore now, I'm actually concerned that she'll get killed or something, we'll argue on the way, she'll embarass me in front of my enemies - so she's a trophy housewife now, nagging me everytime I accidently Fus-Ro-Da the crockery and no sex drive whatsoever. In Fable, wives sometimes give you crap weapons... is that what game programmers think marriage is about!?... monotomy? - sometimes I think it would be cool if she made me a pie without me having to ask, or washed her face, wore a nice dress now and then, ate breakfast in her underwear... anything that you don't already get with man-hands Lydia.
To me, marriage in videogames is usually pointless, and when it has a point, when its a facet of the core gameplay, it can be bloody depressing. I guess I don't understand why people would choose to play a game where relationships are the sole focus, that just seems sad, like when some Animal Crossing bastard psycho analyses you, and get's it completely right.
