I think a lot of PS2 games will just always be cheap. https://www.pricecharting.com/console/playstation-2 The graph on this page shows price barely moving. The bottom of the PS2 price curve was around 2013. Prices have steadily increased since then, but it's been a slow crawl compared to pretty much any other system.
Cool website. I had never seen it before.
The Wii sold much closer to the PS2 than the Gamecube. Do you think its games will also follow a price pattern more similar to the PS2? There are just going to be a lot more Wii games floating around out there than Gamecube games.
