I think this is somewhat an immersion factor.. but I guess part of me is somewhat interested.
Is it possible to develop weather in cities? I often recall Burmecia from FFIX. Can anyone see a pros and cons to this? It seems a little weird that it's rainy in The Black Shroud, but sunny in Gridania... always.
Anyways, I thought this would be a good suggestion. This could be pertinent to quests too, like they used to be in FFXI.
