New releases tend to increase the price for older games in the same series. Gamers are excited for the new game coming out so they buy the older ones too.
A very good example of this is the Resident Evil franchise right before the release of Resident Evil 5 for Xbox 360 and PS3. The chart below shows the resale price of Resident Evil 1 for PS1. There is a very obvious increase in price prior to RE5's release.
The same can be seen with Resident Evil 2, Resident Evil 3, RE Code Veronica, and Resident Evil 4 before March 2009.
In past articles I've analyzed the same price increases in Pokemon games after the DS games launched. And you can see a few more examples below.
Street Fighter Anniversary
Call of Duty Finest Hour (when both CoD 4 and CoD World at War came out).
This same general pattern holds true for many other games. Sometimes the price increase happens more before the new game. While other times it happens more afterwards. But within a month or two of a big release, the past games in that series will almost always see a resale price increase.
How Long Does The Price Spike Last
After a few months the prices usually come back down to normal levels. The chart above for Call of Duty Finest Hour shows the resale prices quickly coming back down in the second month. Metal Gear Solid for PS1 shows the same pattern.
Other games show different patterns. Super Smash Bros Melee starts dropping in price immediately after Brawl launches.
Persona 2 on the other hand only had a small increase in price the month after Persona 4 released and then went back to the same exact price range as before.
How to Use This New Releases Information
Gamers can save some money when shopping for their games or make more money selling some of their collection if they take advantage of this information. If you want to play a game before a new game in the series is released, buy it a couple months early. If you want to sell a game in your collection you can generally get more money for it by selling it the within a month of a new release.
Leave a comment below if you know any other good examples. Or maybe a game that bucks the trend.
