Saltsea Chronicles

There is no one protagonist of Saltsea Chronicles. Instead the game follows the entire crew of a ship in a post-apocalyptic world dotted with islands after a massive flood. The lack of a single main character makes for an interesting adventure game in which every island you visit requires you to pick the crew members you want to explore with, meaning that every island has different ways to approach its challenges since every crew member has their own strengths and weaknesses.
