Imagine a RP where Skuldafn, Midgar City, the National California Republic, Azeroth, The Cyrodilic Empire, etcetera all exist on the same world. . . well, this role play is exactly that. A world of countless possibilities.

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.
WW1 to WW2 is a HUGE time span for weapons, it basically redefined modern warfare today. You can't just say "between ww1 and ww2" since its like a 30 year period where just about everything military changed. Organization, weapons, tactics, leadership, you name it and its been altered.
Again, it doesn't matter if the CE has mages and stuff, the NCR has modern weapons. No amount of armor is going to stop a .50 BMG shot from Anti Material rifle or a missile from a missile launcher or a laser/plasma from an energy weapon or a grenade going off at point blank. While the NCR beat back the BoS, they weren't going at them with sticks and stones, even the Legion and Tribals have guns.
By the logic I'm getting, you're saying that basically the Fire Nation has a chance against Wolfenstien The New Order's Third Reich because the Fire Nation has magic.
