Don't see why in the big 26, we can only be married to one person at a time in Torn City.
Obviously I'm a new player but I think it would bring lots of funny/interesting dynamics to the game, and to me, a system that seems kinda lackluster and dated (The marriage system.)
I don't really see how it'd be overpowered or mess with any of the game meta, but again, I'm very new so let me know if I'm completely wrong. Just a thought lol
