Roblox

Familiars.io is an indie adventure RPG released in 2020 on multiple platforms, developed by a small creator. While it has some cult following due to its similarities to classic Pokémon-style games and was notable when launched for being a lightweight online creature collector, its player base has remained small. Most indie browser RPGs of this style outside major platforms rarely sustain large daily numbers long-term, especially four years after release without ongoing active marketing or major updates.

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.
