I'm hoping its ok for me to start this topic...I'm sure someone will let me know if its not!
Carla asked that vv4 suggestions be just that...and I agree, I love to read through other peoples ideas, so I thought maybe it would be a good idea to have a separate place for discussing them.
Ive noticed a lot of people seem to have a problem with the 'inbreeding' thing. I 'marry' my villagers on paper, however, once the children have grown, I forget who their parents are, so I dont overly care. But I like the idea of having to create homes, courtships, death of partners, and families. And I have to agree with the comments of some others, this is game, so it really should be kept in perspective.
I love the idea of seasons. The variables it could create are amazing. Heavy summer rains that create floods....cold winters that kill gardens (why not have a separate food storage, that the villagers have to fill in preparation for winter)...spring when lots of flowers bloom...and watching the island become bare during autumn.
