I posted a thread a while back about how I think the game could afford some alternative ways to get the "marriage" stardrop, seeing as it's required for 100% completion and many players who don't wanna marry probably don't want to have to marry and divorce an NPC just for the sake of 100% completion. Ideas I posted included single adoption and the addition of more marriage candidates, including options for older players. Someone in the thread posted an interesting proposition, that being an advanced game option to specify whether your character is younger or older. It would change how certain NPCs interact with your character, alter how some heart events play out, and change the marriage candidates available to your character. I think that'd be a great way to implement older marriage candidates as an option.
