Another analysis is that the reason they have the Red mountain in morrowind and the imperial tower in cyrodiil is because during a daedric quest you go very high up in the sky and you can see the imperial tower and red mountain from there.
I worked at blizzard as a Game Design intern there TWICE. Every people I met there have been fantastic. Sad to see that Blizzard is cutting all these jobs, but I guess it's kinda relieving to read that 90% of those was non-game...
