I agree with what you said, except for 2 things:
* Weapons. No guns, and no gun-powder guns. You want to shoot somebody or something with a gun, there's plenty of FPS'ers out there. Besides, people only look at weapons in games from one perspective: how cool it would be to shoot someone.... till they get shot. Then they want more a powerful weapon... till they get shot. Then they want... etc., etc., etc. Sorry, I draw the line at guns.
Sounds like a server setting to me. If you going to have modern architecture in the game (its already there) how can you not have modern weapons
