Alea was started as a new label within Ravensburger in 1999. Each of their games in a particular sized box is numbered in order of publication, yielding their big box series, the Alea medium box series and the Alea small box series. The Alea versions of the games were produced in German. Some of the series were re-printed by Rio Grande Games in English versions of the boxes. Chinatown and Adel Verpflichtet were not.

• The English version of Mammoth Hunters, while having a similar box art style as the others in the series, does not actually have a number 8 printed on the box.
  • Jay Tummelson discusses his reasoning for this break in the numbers being printed on the Rio Grande Games boxes and why he didn't do RGG editions of Chinatown and Adel Verpflichtet on the Boardgame Babylon podcast, Volume 36.
• The Swedish/Finnish edition of Puerto Rico was renumbered #1 by the publisher, and the separator between the author and game name was dropped.
• Different games of the series are published in Dutch:
  • Ra was published by 999 Games. Same box art, no number.
  • Taj Mahal was published by Quined White Goblin Games (QWG). Different box art, no number.
  • Princes of Florence was published by Quined White Goblin Games (QWG). Different box art, no number.
  • Adel Verpflichtet was published by Jumbo. Different box art, no number.
  • Puerto Rico was published by Ravensburger. Same box art, no number.

The first 7 games in the Alea big box series were highly praised on BGG, and are often given as examples of gamers games. All but one, Adel Verpflichtet, rank in the top 250 games on BGG as of March 12, 2008. The following three games have remained substantially lower ranked. The most recent two games, Notre Dame and Im Jahr des Drachen, could be considered a return to form, as both are ranked in the top 60 as of Jul 21, 2008.
