Marriage – is literally going and telling police that you're being with this broad... And that if you're wanted for any reason, her realitives' houses should be checked too in case they're helping you hiding. Also, that same broad can leave you any moment, and you'll have to pay her money for decades, because.
I mean, why in heck would anyone want to legally marry, ever?
In Soviet Union free apartment flats were given to married couples, and the more they have kids – the bigger apartment you're given... But this doesn't work under capitalism. 😁
Dunno, marriage literaly doesn't make sense, not IRL, not in the game.
But generally, having any good endings sounds okay too. Those should be distant though, and ideally allowing you to just live afterwards. Just knowing there's no more plot after some point.
