Endless Ocean: Luminous

VS

Grand Chase

Endless Ocean: Luminous is a 2024 release from Nintendo and Arika for the Switch, building on a recognizable niche series focused on underwater exploration. Although recently released and backed by Nintendo, its genre (exploration/simulation) typically attracts a dedicated but smaller audience compared to action or competitive titles. Early post-launch engagement is likely solid, but the adventure/exploration focus generally leads to moderate, not massive, daily concurrency.

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.
