Each player begins with a small set of cards. Throughout the game, players must save up and purchase cards that will expand their railways and give them the best control over the map. Better railways give you points that count for victory at the end of the game. Trains is fundamentally a deck building game and players of Dominion will see a few similarities between the two, but the addition of the board gives Trains a fresh new take on the deck building genre. Rising Sun adds new cards and new boards to the game so no two games will ever feel too similar.
