Apparently, the slogan “gotta catch’em all” refers to the games as well as pokemon themselves.<br /><br /><img src="http://www.jjgames.com/static/images/all_pokemon_prices_vs_index.GIF" align="middle" alt="graph pokemon game prices"/><br />The graph above shows the average price of all portable pokemon games on a seven day <a href="http://en.wikipedia.org/wiki/Moving_average" rel="nofollow">moving average</a> vs. the <a href="http://blog.videogamepricecharts.com/2007/06/buy-video-games-in-november-not.html">price for all video games</a> during that same time. The data starts in early February, almost three months before the DS games were released, and goes until the end of June 2007.<br /><br />The blue section shows the prices stay relatively even with the overall video game index initially. From the end of February until Pokemon Diamond and Pearl were released on April 22nd (the yellow section) prices start rising and don’t follow the same trends as the rest of <a href="http://www.videogamepricecharts.com">video game prices</a>. For the next month after the release prices fall back into the overall trend and steadily decline at roughly the same pace as the index prices. Starting in the green section though, prices for Pokemon games start increasing again and are nearly 50 percent higher than other video games at that point and 23 percent higher than when they started back in February.<br /><br />What accounts for these big differences in prices and the three separate price increases? Generally, people want to collect all 493 pokemon, which requires them to buy the older games as well as the new one. Or, they enjoy the new ones so much they want to play the older games, too. Whatever the reason, people seem to really increase their buying at three separate times shown on the graph below.<br /><br /><img src="http://www.jjgames.com/static/images/all_pokemon_increase_sections.GIF" align="middle" alt="graph of pokemon game prices" /><br />The first increase is about two months before the new <a href="http://www.videogamepricecharts.com/console/nintendo-ds">DS games</a> release and prices increase about 20 percent in 30 days. The second increase is shorter and not as big, about 11 percent in two weeks. The third price spike starts the day kids get out of school for the summer, May 25, the Friday before Memorial Day. Parents start buying games for their kids once they are out of school and have more time to play. What better way to entertain your kids all summer than a collection quest that requires you to beat at least three different games?<br /><br />The time between the three price spikes are generally decreasing about the same as the overall video game market. Showing that supply and demand for pokemon games and all video game are about the same during these time periods.<br /><br />I plan to continue looking at pricing trends for other old games after the new ones come out to see if this same phenomenon occurs. Does it happen to Spiderman 1 and 2 when the third game came out? What about Final Fantasy X and X-2 when Final Fantasy XII came out? I’m guessing all games show a spike to some degree when a new one in the series arrives, but by how much? Back to the data I go to find out.<br /><br />Try the Subscription <a href="http://www.videogamepricecharts.com">Video Game Pricing Service</a><div class="blogger-post-footer">This is a post from <a href='http://blog.videogamepricecharts.com'>VideoGamePriceCharts.com</a></div>JJ Hendrickshttp://www.blogger.com/profile/12332952027760872601noreply@blogger.com8
