Indie dev Surprised Man created its game The Wager as part of the 72-hour Ludum Dare game jam in December, and has since been expanding on it for an official release.
It's an exploration game in which you explore islands in the open sea with a ship, which translates some of the magic that Colonization used to give you at the start of every game. It also has some great -- and very British -- writing.
As you explore islands, you go on text-based adventures while managing your supplies. It's great fun and can easily eat away hours of your time once you get into it.
