It's a busy night. Everyone talks to someone else, exchanges goods, barters, buys and sells. People prefer to talk to people they know, and newbies, as they call them, have a hard time getting to the heart of the matter. Tonight is not a farmers market, but a busy Saturday night at a trading card shop. People gather from the surrounding area to group together, buy, trade and sell cards and play these collectible card games with each other. It's a community event, where everyone participates in one way or another. The most popular game, Magic: The Gathering, usually attracts the most participants, but other games, such as Yu-Gi-Oh and Pokemon, also attract people. This group is the one that returns, in most cases, time and again to participate in the activities offered. One-off visits aren't too uncommon and new people attend, but most people in the store know each other by name and have relationships that have developed over weeks, months and sometimes years of interactions. Although all cards have fixed values, the trading card economic system is a reciprocal system in which relationships determine interactions because participants usually have more than one interaction with each other. The standard value of each trading card depends on a single factor: supply and demand. The end of the offering is controlled almost exclusively by the owners of the trading card game. The corporations or companies that own the trading card game decide how many cards will be printed, whether there will be another print run of the card, and whether the card will have special appearances. In almost every trading card game, there are inherent levels of rarity built into the… center of the… shredded card. Works Cited "Assorted Magic the Gathering common or uncommon cards."
