Conderining the Maps.

I've always thought it would be terribly cool if the maps changed depending on the season!
Like, if it's winter a snowy ground and maybe some snow flakes flying around.
Spring with a little more blooming and stuff.
Cold / Rainy feeling in autum.

This could give some cool conditions for quests and NMs as well maybe,
besides it being totally awesome imo.
I wonder if that is possible at all tho..
