Prototype (1995, 2006 and 2009)

Some examples of 3 unrelated games with the same name:

Sleepwalker (1991)
Sleepwalker (1993)
Sleepwalker (1999)

Nightshade (1985)
Nightshade (1992)
Nightshade (2004)

And if we exclude subtitles (so not exactly the same name but close enough ;-)):
Myth (1989)
Myth: History in the Making (1989)
Myth: The Fallen Lords (1997)


It's also interesting how similar the logos of the two myth games are (see attachment).

Maelstrom (1992), Maelstrom (ALSO 1992), and Maelstrom although technically the last one has a subtitle.

Same name as an apparently related non-book:
Her Story (game, available on this site)
Her Story (film from 1920, not available on this sits AFAIK)
Her Story (TV show that premiered in 2015)

So, not the same name as another game, but the same name as two unrelated non-games.

Also:
Dragon Quest (video game released in 1986 in Japan)
DragonQuest (tabletop role-playing game released in 1980)
According to Wikipedia, there is also a 1970 novel and a 2009 film with the name as well.

Just thought of another game/non-game collision:
Rust (online video game)
Rust (programming language)

Incidentally, on Reddit, r/rust (the subreddit for the programming language) occasionally gets posts that belong on r/playrust (the subreddit for the video game).

Saboteur (1986, 2004)
Spore (1987, 1991, 2008)

I played the original Saboteur back in the 80s. :-)
