One Piece: Treasure Cruise

Roblox

One Piece: Treasure Cruise is a long-running mobile RPG from Bandai Namco, released in 2014. While the game enjoyed strong popularity due to the One Piece franchise, daily active players have declined in recent years, but it retains a steady, dedicated fanbase globally, especially due to ongoing event updates and a gacha system.

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.
