This is why the "All of Tamriel" idea is best, cos an entire game in Hammerfell or Elsweyr would have the same problem as Morrowind did - too much brown. If it went over multiple maps, or even just had a selection of them, then there would be more variety. Having to adapt to the different fighting styles needed for desert/jungle/temperate would make the game more of a challenge too.
