Roblox

Florr.io is a browser-based indie action game released in 2020 by Matheus Valadares, known for creating other successful io games like diep.io and agar.io. While past io games had massive player spikes, Florr.io's current active player base is significantly lower given its age, niche appeal, and the general decline of the io genre after their peak, but it maintains a dedicated community. A conservative estimate considering ongoing casual traffic is about 10,000–20,000 daily players.

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.
