I'm still unsure at the moment. The world will depend on which household I'm currently playing in my rotation when the EP will be released, but I'll probably try to avoid Oasis Spring.
For the starting seasons, I'm still hesitating between Spring/Summer to continue with the weather we currently have, and see the start of Fall while playing, or just starting directly during Fall. I think it will depend on how seasons progress, and which settings we have. If I'm doing my rotation with one week = one season = one household, I'll most likely start in Spring/Summer. If I'm doing the whole rotation with one season, I'll probably start with Fall, or I wouldn't see any change before a looooong time.
