This is a list of computer and video games that are set in the Old West or that are defined by a Western style, including those that blend Western elements with other genres, such as Space Westerns.
Horror Western, Film noir, Martial arts (genre), anthropomorphic animal characters), neo-Western (Contemporary settings/times), Post-apocalyptic West, Weird West (Also can have supernatural, steampunk, superhero themes), among many others.
It is probably okay to leave 'spaghetti westerns' and some other mixed genres in the traditional section.
See this List of Western subgenres for a comprehensive rundown on numerous types of alternate Westerns.
Also includes delisted games which can't be downloaded anywhere again.
