It would be cool, but I think that might take away from the escape aspect in Animal Crossing. Being able to pop on when it's a gross rainy day and enjoy the sun is always lovely.
yeah kinda ruins the escapism element of the game for me.. i live in northern england so its pretty much rain constantly for all four seasons, and that would suck to play.
I would love that if I lived in a place where I'd get all four seasons. Unfortunately, I don't. It's always hot and humid where I live and we rarely (once every few years?) get snow. It would suck if my game were like that, but the idea is nice. For the most part my game is pretty right on anyway, since it's usually raining IRL whenever it's raining in-game xD
