The Idolmaster: Cinderella Girls

Township

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.

Township is a popular city-building and farming simulator developed by Playrix Entertainment, released in 2013. It has remained widely played, especially on mobile platforms, due to Playrix's strong support and engagement via social media. However, as it is over ten years old, its daily active player base has likely diminished from its peak, though it still maintains significant traction in casual mobile gaming. My estimate reflects its age, the large global reach of free-to-play mobile games, and the continued activity seen in its communities.
