It is a simulation, so yeah.

I did play GTA but not that advanced since I don't have a powerful PC to install and play that, just San Andreas. But this game has a lot of mini-games, a lot of places to go to and a lot of achievements to do, as I said, you will never be limited to the 4 corners of the casino in-game since you will be more entertained by the thrill of going around the map doing what you want to do.
