From the rulebook:

"TIMESTALK is a board game for 4 to 6 players, Ages 14 and up. Approximate playing time is 1 1/2 to 2 hours.
TIMESTALK is a race game (the first player to advance through the "four ages", achieve a successful launch, past the Black Hole and directly into the "arrow of outer space" wins the game), but the race is HUMAN and so the path to success is long and arduous, marked by crises, aggressions, precautions and risk-taking.
Interface all of this with the unpredictable consequences of Timewarps and a Black Hole and you have "A SPACE AGE GAME FOR HUNTERS AND GATHERERS".
