Ship Games

A ship gives a game somewhere for things to accumulate - cargo, damage, distance - which is why these end up being about management as often as about sailing.

Idle Trade Routes is the clearest example, building a network of routes that keeps earning while you're elsewhere. Ship Invaders takes the opposite approach and makes the vessel something to defend. Ship & Fish is the gentler one, and Stickman Escape - Plane and Ship uses the ship as somewhere to get out of rather than something to run. They've little in common beyond what they're set on, so treat the tag as a list rather than a recommendation.

There are 4 free games under this tag, all playable in the browser with nothing to install, and they've little in common beyond what they're set on.

The management end is Strategy games, and Adventure games covers the ones you're exploring rather than running.
