The T.I.M.E Agency protects humanity by preventing temporal faults and paradoxes from threatening the fabric of our universe. As temporal agents, you and your team will be sent into the bodies of beings from different worlds or realities to successfully complete the missions given to you. Failure is impossible, as you will be able to go back in time as many times as required.
T.I.M.E Stories is a narrative game, a game of "decksploration". Each player is free to give their character as deep a "role" as they want, in order to live through a story, as much in the game as around the table. But it's also a board game with rules which allow for reflection and optimization.
I personally love this game, and have played every single game in the series. Its been a stand out gaming experience of the last decade.
