When the sweethearts go off to college and leave you "a little something", it's always the same boring, basic necklace that every girl already has a thousand of. I think it would be neat if each boy gave a special, unique gift after he leaves- something you can't get anywhere else in the game, or from any other boy. It can even represent something about him- like Walsh the Warewolf might leave you a fur coat, or Dante the Dancer could leave you some ballet slippers.
It would make collecting the sweethearts WAY more fun, and more competitive and challenging as girls have more of a motivation to steal them from each other, and try to keep pampering them until they get their gift at the end. Plus, I seriously think we are all getting sick of seeing the same stupid necklace that nobody wears anymore.
I really hope you guys use this idea, because I think it would be awesome!
