Make Sail is an indie exploration game where you can craft any ship you can imagine and set sail for the seas! Explore a procedurally-generated stunning world and get on foot to explore remote islands. Get new pieces, upgrade your ship, and explore farther islands. It’s probably the most rewarding exploration ocean sim I’ve ever seen.
In Other Waters is an underwater exploration game where you explore the depths of an alien planet as a computer AI guiding a xenobiologist. The game is a unique take on the exploration concept and focuses on storyline and narratives as well as questioning the relationships between AI and human lifeforms. It’s a fresh new take.
