City of Heroes

Slither.io is a well-known browser-based arcade game that launched in 2016 and achieved significant viral popularity due to its simple, addictive gameplay and ease of access on web and mobile. While its peak has long passed, browser games of this type typically retain a steady, modest player base over time. Current daily players are likely in the tens of thousands given its enduring casual appeal and presence across platforms.

City of Heroes was a well-known superhero MMORPG launched in 2004 and shut down officially in 2012, but an active community revived it through private servers (notably Homecoming). Activity on these private servers has stabilized, with daily active players generally in the low thousands range (estimated 5,000–10,000 daily as of 2024 based on community server stats and ongoing niche interest). As an MMORPG with a persistent world, it retains a loyal core community but no longer draws mainstream MMO crowds.
