Black Russia

VS

DayZ

Black Russia is a relatively well-known open-world multiplayer RPG, especially popular in Russian-speaking markets. It combines action, racing, and simulation elements, and is available on mobile platforms. Despite not being from a major international publisher, it has maintained a steady mobile player base in its niche. Given game trends for open-world/sandbox RPGs on mobile, and a lack of recent western attention or major updates, a conservative estimate is around 10,000-20,000 daily players.

DayZ is a well-known open-world survival game by Bohemia Interactive, released in late 2018. It remains popular within the survival genre and typically holds a strong concurrent player base, especially on PC with additional activity on consoles. Its age means it's past its peak, but it maintains a loyal community and steady content updates, resulting in an estimated 45,000 daily active players across platforms.
