Interesting, but there is a business reason why;
Bethesda had to pay Nothing in royalties to anyone for using the national land marks in the game, the same holds true for all the town and city names. Notice however you will not find any Company names from today - precisely for that reason.
Do you have ANY idea how much the Real Las Vegas casino's would charge in royalties to have their names in the game?
If that wasn't enough to stop them, I frankly don't think the Casino's would want themselves portrayed in this game - as in most cases the portrayal of the casino owners is frankly unflattering in the extreme. Can you imagine the reaction from Modern day casino's to the storyline behind the owners of the Tops? Gamorah? Ultra-Lux? Every one of the casino's in New Vegas is dark, does extremely evil things and in some cases, outragous things. I somehow doubt that the modern day casino's would want themselves portrayed like that, and even is so, would have charged ALOT of money for using their names.
Bethesda/Obsidian did the only rational thing to do - make up the casinos.
Oh, I agree 100%. they would have charged to use their names. But, when I saw that the next installment in the Fallout series was called Fallout: New Vegas that takes place in and around a post apocalyptic Las Vegas strip, that is what I figured they did. But that is not what we got.
I'm just suggesting that it was a disappointment and a bit misleading. Instead of Fallout: New Vegas how about....Fallout4??? "The next installment of the critically acclaimed Fallout series follows the story of a wasteland messanger through the Mojaive Wastelands and into The Strip. A City of corruption and intrigue loosely based on modern day Las Vegas....blah, blah, blah...
That would have been a better representation.
Like I said. Still loving the game but i still don't feel like I've played a fallout game that takes place in Las Vegas as I was led to believe FNV was supposed to be.
