I don't know if anyone suggested it for VV3 but I asked about it for VV2. Night Time, why is it never dark on the island. OK, just if you put the difficulty on hard or make a very hard level, then it cold get dark and villagers could gather around the fire or go indoors to aviod animals and the cold. Also would be a great time for villagers to share stories and pass along oral history to the lil ones. Rain? has any one ever seen it rain, it's a tropical island after all. Pets, the ideas are endless... There are lots of very good suggestions going up here.
I realy like (dare I say LOVE) this game.
