Grand Chase

Merc Zone is a web-based first-person shooter developed by Blue Wizard Digital, known for lightweight, accessible online action games. Web-based shooters tend to have modest but steady user bases, mostly among casual and school-age audiences. The game is not a major, widely-publicized title, so daily players likely remain under a thousand, fitting the lifecycle for smaller browser shooters from indie developers.

Grand Chase is a well-known side-scrolling action MMORPG originally developed by KOG Studios. Although the classic PC version was shut down in most regions years ago, the mobile relaunch (Grand Chase: Dimensional Chaser) and a Steam version have seen some limited success since 2017. Due to its age, niche appeal, and relatively modest marketing outside its core market (primarily Southeast Asia and Latin America), I estimate its daily active player base to be low thousands. The game does have persistent multiplayer elements and instanced co-op/competitive modes, qualifying as an MMO.
