Marvel Rivals has a massive leg up on other hero shooters in that it has a massive backcatalog of characters to work with. Spider-Man’s supporting cast alone would easily fill up a roster, and NetEase has access to all of them, plus beloved IPs like X-Men, the Avengers, Fantastic Four, and more. These characters, their history, and the fans’ attachment to them are all huge parts of why the game has been rocketing up the Steam and Twitch charts with no signs of slowing down.
