I find this Wikipedia category weirdly fascinating: List of Las Vegas Casinos That Never Opened.

A sample:

Titanic
Themed after the doomed luxury liner RMS Titanic, this resort was to have been modeled after the ship and would have been 400 feet (120 m) long with 1,200 rooms, standing across the street from the Sahara Hotel and Casino. The project was rejected by the Las Vegas City Council.

World Trade Center
To have been located at 925 East Desert Inn Road, Las Vegas.

Leonard Shoen, co-founder of U-Haul truck rental, purchased the property of what had been the Chaparral Hotel & Casino in 1996, renovating it into the World Trade Center Hotel. A gaming license was applied for, but when it was discovered that two of Mr. Shoen's closest partners were convicted felons, the application was denied in 1998. He withdrew his application, and later died in a car crash in 1999 that was ruled a suicide. Cards and gaming chips were produced for the World Trade Center Casino, but were never used.^[3] The property has since been demolished and is now vacant. The old World Trade Center Casino site is now a parking lot, part of the Sands convention center annex.

World Wrestling Federation
A casino resort themed after the World Wrestling Federation was proposed for a property near Interstate Highway 15 across from Mandalay Bay. The project never went past the proposal stage. WWE also proposed to open on the property best known as the Debbie Reynolds Hotel and Casino, but now known as the Royal Resort Hotel and Casino.
