The Idolmaster: Cinderella Girls

VS

Pony Town

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.

Pony Town is a social sandbox game, launched in 2016, focused on creative interaction and customization rather than traditional progression. It has a dedicated but niche community, mostly sustained via word of mouth and social platforms. Its web- and mobile-based accessibility helps retention, but it remains a relatively small game by mainstream standards, with an estimated daily active user base of about 5,000.
