Roblox

PowerZ is an educational open-world adventure game for children, released in February 2021. As a niche, education-focused title from an indie studio with modest international reach, its cross-platform availability (mobile/PC) helps retention but not at mainstream scale. At approximately 4.5 years old without major global breakouts, a conservative daily active player estimate is in the low thousands.

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.
