Aion

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.

Aion is a fantasy MMORPG released by NCsoft in 2008. It had significant popularity in its early years, especially in Asia, but has seen a steady decline in Western markets due to age, competition, and lack of major expansions. NCsoft still supports the game and runs classic servers, which help retain a niche but passionate player base. Current daily active players are likely in the low thousands globally, maintained by a dedicated core community.
