Escape from Tarkov

The Idolmaster: Cinderella Girls is a long-running mobile/social idol management game launched in 2011. It remains notable in Japan with an active niche fanbase, regular events, and ties to the broader Idolmaster brand, but is well past its peak popularity. Its daily active players are likely in the tens of thousands, supported by ongoing in-game events, but fallen off from earlier years. Not an MMO, as it lacks persistent world and massive real-time multiplayer interactions.

Escape from Tarkov is a hardcore tactical shooter with survival and RPG elements, released in 2017 by Battlestate Games. Despite being several years old and not yet fully released as a 1.0 version, it retains a strong, dedicated player base due to its unique, high-stakes gameplay loop and regular content wipes. However, its niche appeal and high difficulty prevent mass market adoption, leading to a moderately sized but stable daily active player count.
