Pokémon Trading Card Game Online

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.

Pokémon Trading Card Game Online launched in 2011 and has been largely superseded by Pokémon TCG Live (2023). The original remains online but with a much-reduced population. While once popular, most activity has migrated to the new platform. Given its age and replacement, a DAP in the low thousands (~4,000) is a reasonable estimate. Its genre (online card game) means its numbers can persist longer but decline after official support and community interest shift.
