Buying GameCube games from other regions

This blog post was inspired by discovering that Pokémon Box: Ruby & Sapphire, a legendarily rare and expensive GameCube game in the United States (>$2,500 USD), could be purchased complete-in-box (CIB) in Japan for $50 USD. That's a savings of $2450, or ~98% of the US price. This is a somewhat extreme example: in the US market Pokémon Box was only sold online and at a single store: the Pokémon Center in New York City. This big price difference between regions got me thinking: what other games are cheaper in other regions and by how much? Please note that the below data was taken from Pricecharting on August 30th, 2026. Shipping costs aren't included in the price, shipping from Japan to the US is typically $15-$20 USD on eBay, but many games are already imported to the US.
