Player collecting seems like a fairly simple concept. Trying to collect all of a player's cards. There are many variations on player collecting. The true obsessives chase everything featuring their player, going so far as to include cards in which their player is featured in the action shot (sometimes known as Cameos). Other player collectors chase after cards with a print run of more than 5 or 10, or everything except 1/1 cards. Collecting only GameUsedCards or autographs is another variation. After a player is chosen, it is basically up to the collector to define the parameters of their collection.
