Sea & Ocean MMOs

For some MMOs, the ocean isn't a side feature — it's the entire game. Sea and ocean MMOs build the core experience around sailing, ship combat, exploration, and survival at sea, with dry land often reduced to ports, outposts, or the occasional stop between voyages rather than the main stage. Weather, currents, ship damage, and the sheer unpredictability of open water replace the usual dungeon-and-quest loop with something closer to a maritime adventure. This tag covers MMOs centered on the sea, where sailing the map isn't a detour from the game — it is the game.
