Do you include:
* Every single game featuring Spider-Man, even in a small role? This would be a very large number, including games like "Marvel Ultimate Alliance" and "Marvel vs. Capcom" series where Spider-Man is a playable character.
* Just games with Spider-Man as the main protagonist? This would still be a lot of games, spanning across different platforms and genres.
* Just games released within a specific timeframe?
* Just games considered "canon" within the Spider-Man universe?
To give you a better idea:
* There are over 40 Spider-Man games released throughout the history of video games. This includes games for various platforms, from arcade machines to modern consoles.
* Some of the most popular and critically acclaimed Spider-Man games include: "Spider-Man 2" (2004), "Spider-Man: Shattered Dimensions" (2010), "The Amazing Spider-Man 2" (2014), and "Marvel's Spider-Man" (2018).
To give you a more specific answer, you need to be more precise about what kind of Spider-Man games you are interested in.
