Most of the world has heard by now that Grand Theft Auto IV came out April 29th and it was just announced that in the first week the game sold 6 million copies worldwide. The number of games sold for the 360 and PS3 hasn't been announced yet but so far Xbox 360 owners have been buying more of the classic GTA games than Playstation 3 owners. Prices for Grand Theft Auto San Andreas, GTA Double Pak, and GTA Trilogy have increased more on Xbox than Playstation 2.
Buying all three older Grand Theft Auto games released on Xbox would cost $76 now instead of $64 in March, an 18% increase. Buying the same Playstation 2 GTA games would cost $33 now and were $30 in March, which is an 10% increase. If you look at all the PS2 GTA games, including the ones that were not released on the Xbox, you see only a 3% increase from March to May. During this time of year video game prices usually go down.
This difference is either caused by increased demand, limited supply, or a combination of the two.
On the supply side the Xbox game supply is limited while the PS2 supply can increase. The Playstation 2 is still around and retailers are continuing to sell new games. You could find many of these PS2 GTA games brand new at stores. This stops the used prices from increasing very much because the supply can increase too. Xbox games on the other hand are not as easy to find new. Many retailers stopped selling them so the supply of these games is static.
In terms of demand, the Xbox 360 has sold more consoles than the Playstation 3. Assuming the game sells the same proportionally on both systems there are more GTA IV 360 owners. Which means there are more 360 owners who are looking to play the classic GTA games.
