Fallout: New Vegas Mod — Run The Luck 38 Casino & Hotel
You must manage the finances, hire employees, and control every aspect of the Lucky 38’s operation, including the quality of patrons you serve and the services you provide. Similar to one of those Tycoon games, you grow your business, extend your influence, and face the consequences of your decisions.
The mod even includes a three-part quest that involves rescuing the remnants of the Enclave.
Check out this video, and mind the terrible FPS:
The best time to play Run the Lucky 38 is after you have the main quest completed.
