Age of Water

Roblox

Age of Water is a post-apocalyptic open-world game by Gaijin Entertainment (known for War Thunder). It released in early 2025, so it is still relatively new, but not a massive blockbuster. Gaijin's niche appeal and the open-world/sandbox elements suggest a moderate but not huge player base. Its MMO status is debated, but it appears to have persistent world and multiplayer interaction, fitting the basic MMO criteria; however, it is on the lower end of the active player spectrum for MMOs.

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.
