Sword Art Online: Unleash Blading

Roblox

Sword Art Online: Unleash Blading is a mobile RPG by Bandai Namco released in late 2019. While it leveraged the popular SAO anime IP and initially saw strong downloads, it is now over 4 years old—a lifespan where mobile anime RPGs typically experience significant playerbase decline unless they remain breakout hits. Bandai Namco's ongoing support keeps a modest, mostly niche community engaged, but overall activity is much lower than at launch.

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.
