I remember someone else trying this a while ago and I'll be bringing up the same point as I did then: how are you going to balance it?

I can't imagine the Cyrodilic Empire's legions and swords doing too well NCR's power armor and modern weapons.
How are the elves of LOTR supposed to fight off the Eldar from 40k?
What is stopping the fire nation from rolf-stomping over everyone else?
I can't imagine anyone doing too well against the Galactic Empire considering they have near infinate manpower reserves, lasers and the Death Star + Star Destroyers.
