Planet Arkadia

VS

Roblox

Planet Arkadia is a planet within the Entropia Universe MMO, released in 2011. As a side world in a niche, aging real-cash economy MMO, it likely retains a small, but committed player base. Entropia Universe as a whole is estimated to have a few thousand daily players, with Arkadia as one of its many planets likely drawing a small subset of that population.

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.
