Hero Siege

Roblox

Hero Siege is an indie hack-and-slash action RPG released in 2014. While it has a loyal fan base and supports multiplayer, it's not supported by a major publisher and is nearly a decade old. Player retention is likely moderate, with much lower daily activity compared to its peak, but some ongoing interest due to regular indie updates and seasonal events.

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.
