For 2003, 75 gamers and one gaming group provided the data his list is based on -- so the list can be accurately described as reflecting the games that serious gamers play. According to Jackson's data, the most-played game of 2003 was Puerto Rico, a strategy game that was my pick for the best game of 2002 and is third on my list of the Top 10 Must-Have Games.
Gamers sent Jackson two lists: one that reflected how many games they played 10 or more times, and one that reflected how many games they played 5 to 9 times. Jackson compiled this data and created the following lists.
To calculate each game's point total, he awarded games 5 points for each gamer who listed a game as something they'd played 5+ times, and 10 points for each gamer who listed a game as something they'd played 10+ times. Percentage numbers refer to the overall percentage of gamers who listed a game (both 5 and 10+ plays).
