Personally I am hoping that one of the first mods to come out for Empire will be one adding South America, Africa and Australia to the campaign map (and maybe South East Asia too, although China and Japan may be a bridge too far). Hopefully simply adding large swathes of land to the campaign map will be easier this time around, especially since CA have announced there will no longer be an upper limit to the number of provinces.

Oh, for a nice spiffy WYSIWYG campaign map editor to be included with the game!
