It's pretty, but I agree that it would only work well with one or at most two seasons... Personally, I'm glad that they concentrated on ensuring that weather works with all worlds, and release this separately, rather than making the EP that bit more bloated and probably expensive and glitchy... I don't really buy store worlds (although I'm often tempted by the features that come with them), as I think they're kind of expensive for what they are... Having said that, it does look beautiful, and will obviously work very well with Seasons... I can't imagine it ever getting cold enough to snow there though!
