Nin Online

VS

Roblox

Nin Online is a persistent online RPG inspired by Naruto, known within niche anime and indie MMO communities. While never achieving mainstream status, its community-driven approach and unique setting have helped it maintain a modest but steady player base. Given its indie nature and lack of major publisher support, the player count is estimated to be in the low hundreds daily.

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.
