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.
