Roblox

The Idolmaster: Cinderella Girls - Starlight Stage is a popular Japanese rhythm/gacha mobile game from Bandai Namco and Cygames, originally released in 2015. While past its peak, it remains active thanks to strong franchise loyalty, frequent updates, and ongoing events. However, age and competition from newer idol games have led to a moderate but steady daily player base, focused mainly in Japan.

Roblox is a massively popular sandbox platform, released in 2006 but continually updated and widely adopted by younger audiences globally. It consistently reports tens of millions of monthly active users, with peak daily actives usually around 5–10% of monthly users. Recent filings and reports indicate Roblox has over 60 million daily active users, but this covers global user logins across many devices and experiences. Adjusting conservatively for reporting and engagement variance, daily actives typically exceed 50 million worldwide, but simultaneous users generally peak in the hundreds of thousands to low millions. As a platform with persistent worlds, it fits the broader MMO definition.
