Most Snow?

Any world that looks like it, I'd say. I haven't played in all worlds enough to be sure, but I'd say that Windenburg, Brindleton Bay and San Myshuno get much snow, as well as Forgotten Hollow and Glimmerbrook. Newcrest might be a safe bet as well. Those with the least snow are the obvious ones like Sulani (duh), StrangerVille, Oasis Springs and Del Sol Valley (though I've seen snow in the latter ones on rare occasions). If you want much snow, I'd move to Windenburg, Myshuno or Glimmerbrook.
