Its no secret that Marvel Rivals, NetEases team-based hero shooter, is a hit, garnering over 20 million players in its first month of release. The results are all the more impressive considering Blizzard Entertainments Overwatch 2 is still going strong, but the real question is: How much has the former eaten into the latters success?Pretty significantly, at least on Twitch. According to SteamCharts, Overwatch 2 saw a peak viewership of 64,970 viewers in the last 30 days a significant drop from the 125,279 peak viewers in November. Its worth noting that November 24th saw the finals of the Overwatch Championship Series 2024.Meanwhile, Marvel Rivals saw a peak viewership count of 275,521 in the last 30 days. The gap grows even more when comparing the past seven days, with Rivals at 140,039 peak viewership and Overwatch 2 struggling at 23,260 viewers. Of course, with the former garnering so many players, its perhaps unsurprising to so many content creators and streamers jumping ship.The disparity in viewership may continue since Season 1 of Marvel Rivals arrives this month. It will include the Fantastic Four as new heroes their first trailer debuts on January 6th.
