Today I was looking for some of my favorite childhood titles such as Super Smash Bros Melee, Mario Kart Double Dash, Pokemon XD and etc. I looked on Gamestop and they barely had them, and most of them were in the 20's 30's or 40's! So then I checked on amazon, same thing. Everywhere I look on the web, its expensive. Why are the favorite such as Super Mario Bros or Mario Kart cheap? There have been many other titles in the series, so why hasn't the price gone down. If so, could someone link me to a cheaper source to buy gamecube games?
