No. I disliked the fact that Cyrodill wasn't a jungle in the first place. I don't want them to change the climate again.
I can feel for that swag. What I disliked about that was there was no in-game reason for that ... the countryside was more like the local park than partially untouched primeval forest or jungle. If you had seen some of the Islands off the Coast of Seattle and Washington State before the loggers decimated them ... truly spooky.
However the obvious call given the above is Skyrim
I don't think MK was talking Easter Eggs, but if he was there might be Mana in the Desert - in that way you could have 'magic-snow' falling from the skies in the deserts of either Elsweyr or Hammerfell.
But seriously, Shoegorrath might do that anywhere with frogs, blood, moonsugar or rubber duckies. :twirl:
