Thanks for the review!
The motivation to explore is not defined indeed and we had no strong one to put in the game rules as "default", but maybe adding a way to define it collectively would add to the game. That's an important step of the game tho and it surely needs to be put there. Maybe different PCs have their own motivation to be sailing there ("Labamba", another game of this contest solves that same kind of problem in a quick and elegant way!)
Grazie a te :D
