While bearing the label "Second Edition", Destination: Neptune (Second Edition) is actually an expansion for Destination: Neptune as it contains only the material needed to play the most recent version of the game, with components from the base game being required as well. This second edition plays more quickly, is easier to learn, and is much better for two players (compared to the first edition). However, the reward for being grounded in science is still at the core of the game! The new attribute cards vary each game, and the rules also provide a number of options for varying the games even more!
