This complex board game was voted as "the best board game ever made" by 'Board Game Geek' users.
Rob Daviau was inspired by the 'Pandemic' board game and created 'Pandemic Legacy' -- a game that could take months to complete. The complex board game has "12 missions, five dossiers, eight boxes, four evolving diseases and a deck of legacy cards." With these items, the goal of the game is to seek a cure for the diseases, which is made difficult as they continue to spread throughout the game. Changes to the board are permanent, making each progressing mission more difficult and past mistakes impossible to erase.
Playing Pandemic Legacy may go on for a long time, but is worth the unique experience.
