Pioneers will be a turn-based game with RPG elements. It's a game where you start by assembling your exploration party with men with different abilities and skills. Every man counts and every skill counts. You need someone who's good with weapons and hunting, someone who is good with carpentry, someone who can draw maps, someone who could easily learn native languages and so on. Once that's done, you put them on a ship and head for some unknown land.
This is the part where you sail out of the starting town and go about the world. Some simple sailing mechanics apply. Once you reach some land you can co into the exploration mode.
